能力倾向模拟测试一
答案:C
解释
Zone of the entire surface = 2(Lb+ bh +Lh) = 2 (24*14 + 14*15/2 + 24* 15/2) cm2 = 2(336+105+180) cm2= (621*2) cm2 = 1242 cm2
第2题 - 一个长方体的长、宽、高之比为6:5:4,其总表面积为33300 cm2。它的体积是多少?
答案:B
解释
Let length = 6x cm, breadth = 5x cm and height = 4x cm Whole surface area = 2(lb+ bh + lh) =2 (6x*5x + 5x *4x + 6x *4x) cm2 = (148x2) cm2 ∴148x2= 33300 ⇒x2 = 225 ⇒x = √225 = 15 cm ∴L= 90 cm , B= 75 cm and h= 60 cm ∴Volume = (L*b*h) = (90*75*60) =405000cm3
答案:C
解释
Length of the diagonal =√ (L 2+ b2+ h2)= √[ (30)2 +( 24)2+(18)2] = √ (900+576+324) =√1800= √900*2 = 30√2 cm
答案:C
解释
Required length = √[(8)2 +(6)2 +(2)2]=√104 cm =√4*26 =2√26 cm.
答案:A
解释
Required length = √[(5) 2+(4) 2+(3) 2]=√(25+16)+(9)=√50m =√25*2 m =5√2m
答案:D
解释
L*b= 6500cm2 , L*b*d=2.6m3=(2.6*100*100*100) cm3 ∴ d = (2.6*100*100*100)/6500 cm = (2.6*100*100*100)/6500*100 = 4m ∴ Depth = 4m
答案:B
解释
Volume of wall = (400*300*13) cm3 Volume of each bricks = (20*12*6.5) cm3 No. of bricks = (400*300*13 /20*12*13)*2 = 1000
第8题 - 一个长24米,高8米,厚60厘米的墙是由砖块砌成的,每块砖的尺寸为24厘米*12厘米*8厘米,已知墙体10%是砂浆。需要多少块砖?
答案:B
解释
Volume of wall = (24*8*60/100)m3 =576/5m3 Volume of bricks = (90% of 576/5) m3= (90/100*576/5) m3= (144*18/25) m3 Volume if 1 bricks = (24/100*12/100*8/100) m3 Number of bricks = [(144*18/25)*100/24*100/12*100/8) = 45000
答案:A
解释
Let the time taken by A be x hrs. Then, time taken by B = (x-20/60) hrs = (x-1/3) hrs Ratio of speeds = inverse ratio of time taken ∴3:4 =(x- 1/3): x ⇒3x-1/3x = 3/4 ⇒12x- 4 = 9x ⇒3x= 4 ⇒x= 4/3 hrs Required time = 4/3 hrs.
答案:A
解释
Let c speed be x meters/min. Then, B speed=3x meters /min and A speed =6x meters/ min. Ratio of speed of A and C =ratio of times taken by C and A 6x:x=42:ymin⇒6x/x=42/y⇒y=42/6min=7 min.
第11题 - 两列火车的速度比为7:8。如果第二列火车以5小时行驶400公里,则第一列火车的速度是多少?
答案:A
解释
Let the speed of first train be 7x km/hr. Then the speed of the second train is 8x km/hr. But speed of the second train=400/5km/hr=80 km/hr ∴8x=80⇒x=10. Hence the speed of first train is (7*10) km/hr=70 km/hr.
第12题 - 一辆汽车以恒定的速度行驶715公里。如果汽车的速度提高10公里/小时,则行驶相同距离的时间将减少2小时。汽车的初始速度是多少?
答案:C
解释
Let the constant speed be x km/hr. Then, 715/x-715/(x+10) =2⇒1/x-1/(x+10) =2/715 ⇒(x+10)-x/x(x+10) =2/715⇒x(x+10) =3575 ⇒x2+10x-3575=0⇒x2+65x-55x-3575=0 ⇒x(x+65)-55(x+65)=0 ⇒(x+65)(x-55)=0 ⇒x=55. ∴Original speed of the car is 55km/hr.
答案:B
解释
Suppose the two trains meet after x hours. Then, 30x+27 x= 342 ⇒ 57 x = 342 ⇒ x = 342/57 = 6. So the two trains will meet after 6 hours.
第14题 - 一个学生以5/2公里/小时的速度从家步行上学,迟到6分钟。第二天,他将速度提高到1公里/小时,提前6分钟到达学校。学校离他家有多远?
答案:B
解释
Let the required distance be x km. then, x/ (5/2) - x/ (7/2) = 12/60 ( ∵difference between two times is 12 min.) ⇒ 2x/5 - 2x/7 = 1/5 ⇒ 14 x-10 x = 7 ⇒ 4x= 7 ⇒ x= 7/4 Required distance = 7/4 km
第15题 - 如果一个学生以5公里/小时的速度从家步行到学校,他将迟到30分钟。但是,如果他以6公里/小时的速度行走,他将只迟到5分钟。学校离他家有多远?
答案:D
解释
Let the required distance be x km. then, x/5 - x/6 = 25/7 (difference between two times is 25 min.) ⇒ 12x- 10 x = 25 ⇒2x = 25 ⇒ x= 25/2 km = 12.5 km
答案:B
解释
Given exp.= √248 +√52+12 = √248+ √64 = √248+8 =√256 = 16
答案:B
解释
(√32+√48)/( √8+√12) =(√16*2 +√16*3)/ √4*2 +√4*3) = 4√2+4√3/ 2√2+2√3 = 4(√2+√3)/ 2(√2+√3) =2
答案:C
解释
(√24+√216)/√96 = (√4*6 +√36*6)/ √16*6 = (2√6+6√6)/4√6 = 8√6 /4√6 = 2
答案:C
解释
√8/3 = √8*3/3*3 = √24/3 =4.898/3 = 1.633
第22题 - 已知√3 = 1.732,则3 + √6 / (5√3 - 2√12 - √32 + √50) 的值是多少?
答案:D
解释
Given exp = 3+√6/(5√3-2√4*3-√16*2+ √25*2) = 3+√6/(5√3-4√3-4√2+5√2) = (3+√6)/( √3+√2)*( √3-√2)/( √3-√2) = 3√3-3√2+√18-√12/(3-2) =(3√3-3√2+√9*2 -√4*3 )= (3√3-3√2+3√2-2√3) =√3= 1.732
答案:B
解释
Let there be x men originally. X man finish the work in 60 days and (x+8) finish it in 50 days. X man finish the job in 60 days. ⇒ 1 man can finish it in 50 (x+8) days. ∴ 60 x = 50(X+80 ⇒10 x= 400 ⇒x = 40 Hence, there were 40 men originally.
答案:C
解释
Ratio of time taken = 1/3 : 1/4 = 4:3
第25题 - 一个男人和一个孩子一起完成一项工作需要24天。如果前6天只有男人工作,则这项工作在26天内完成。孩子单独完成这项工作需要多长时间?
答案:D
解释
Work done by (man + boy ) in 20 days = (1/24*20)= 5/6 Remaining work = (1-5/6) = 1/6 1/6 work is done by boy in 6 days. Whole work will be done by the boy in (6*6) = 36 days
答案:D
解释
1 man = 3/2 boys , 8 men = (8*3/2) boys = 12 boys (4men + 9 boys) = (4*3/2 +9) boys = 15 boys Now, 12 boys dig it in 20 days. 1 boy digs it in (20*12) days. 15 boys will dig it in (20*12)/15 days = 16 days
第27题 - 8个男人可以在12天内完成一项工作。4个女人可以在48天内完成这项工作,10个孩子可以在24天内完成这项工作。10个男人、4个女人和10个孩子一起完成这项工作需要多长时间?
答案:D
解释
8 men 1 day work = 1/12 ⇒1 man 1 day work = 1/96 4 women 1 day work = 1/48 ⇒1 women 1 day work = 1/192 10 children 1 day work = 1/24 ⇒1 child 1 day work = 1/240 (10 men + 4 women +10 children)'s 1 day work = (10/96 + 4/192 +10/240) = (5/48+ 1/48+ 1/24) = (5+1+2)/48 = 8/48 = 1/6 So, they can finish the work in 6 days.
第28题 - 一个男人、一个女人和一个孩子一起完成一项工作需要3天。如果男人单独完成需要6天,孩子单独完成需要18天,那么女人完成这项工作需要多长时间?
答案:A
解释
(1 man+ 1 women +1 boy ) 1 day work = 1/3 Suppose the women alone can do it in x days. Then 1/6 +1/x+1/18= 1/3 ⇒4/18 +1/x = 1/3 ⇒1/x = (1/3- 2/9) = 1/9 So, 1 woman can do the work in 9 days
答案:D
解释
(9*7) men working 1 hr a day can finish the work in 15 days. 63 men finish it in 15 days. 1 man can finish it in (15*63) days. (6*9) men can finish it in (15*63)/ (6*9) days = 35/2 days
第30题 - 9个孩子可以在360天内完成一项工作。18个男人可以在72天内完成同样的工作,12个女人可以在162天内完成同样的工作。4个男人、12个女人和10个孩子一起完成这项工作需要多长时间?
答案:B
解释
9 children 1 day work = 1/360 ⇒1 child 1 day work = 1/3240 18 man 1 day work = 1/72 ⇒1 man 1 day work = 1/1296 12 women 1 day work = 1/162 ⇒1 women 1 day work = 1/1944 (4men +12 women +10 children) 1 day work = (4/1296+ 12/1944+10/3240) = (1/324+1/162+1/324) = 4/324 = 1/81 Hence they can finish the work in 81 days.
答案:B
解释
10 women 1 days work =1/8 ⇒1 women 1 day work = 1/80 10 children 1 day work = 1/12 ⇒1 children 1 day work = 1/120 (6 women + 3 children) 1 day work = (6/80 +3/120) = (3/40+ 1/40) = 4/40 = 1/10 So, they can finish the work in 10 days.
答案:D
解释
5 men 1 day work = 1/19 ⇒ 1 man's 1 day work = 1/95 9 women 1 day work = 1/19 ⇒1 women 1 day work = 1/171 (3 men + 6 women) 1 day work = (3/95 + 6/171) = (27+30)/855 = 57/ 855 = 1/15 ∴ 3 men and 6 women can finish the work in 15 days.
答案:A
解释
Let the capital be Rs. x. then, (x*23/2*1/100*1) ?(x*10*1/100*1) = 55.50 => 23x/200 ?x/10 =111/2 => 23x-20x =11100 => 3x= 11100 => x = 3700 Hence, the capital is Rs. 3700.
答案:C
解释
Let the capital be RS. x. then (x*8/100*1) ?(x*31/4*1/100*1) = 123/2 => 2x/25-31x/400 = 123/2 => 32x-31x = 24600 => x= 24600 Hence, the capital is Rs. 24600.
Q 35 - 佣金运营商允许向金融专家退款 2%,而组织则支付 15% 的投机利息。金融专家在其投资中实际获得的溢价率是多少?
答案:D
解释
Instead of Rs.100, the investor invests = Rs. (100-2) = Rs. 98 Instead of Rs. 98 = Rs. 15 Interest on Rs. 100= Rs. (15/98*100) = Rs. 750/49
Q 36 - 一共贷款 10000 卢比,一部分以 8% 的利率贷款,其余部分以 10% 的年利率贷款。如果每年的平均利息为 9.2%,那么以 10% 利率贷款的金额是多少?
答案:A
解释
Ratio of investments = 0.8: 1.2: = 2:3 Money at 10% = Rs. (10000*3/5) = Rs. 6000>
Q 37 - 一共贷款 5000 卢比,一部分以 6% 的利率贷款,一部分以 9% 的简单利息贷款。如果总年利息为 390 卢比,那么按给定利率贷款的金额比例是多少?
答案:C
解释
Let the money invested at the two rates be rs. x and Rs. (5000-x) Then, (x*6/100*1) + (5000-x) *9/100*1 = 390 => 3x/50 + 9(5000-x)/100 = 390 => 6x+45000-9x = 39000 => 3x= 6000 => x= 2000. Required ratio = 2000:3000= 2:3
答案:D
解释
Let the rates be x% p.a. and Y % p.a. Then, (5000*x/100*2)- (5000*y/ 100 *2) =25 => 100(x-y) = 25 => x-y =0.25 Required difference in rates = 0.25% p.a.
Q 39 - A 以 12% 的年利率获得 8000 卢比的简单利息,B 以 10% 的年利率获得 9100 卢比的简单利息。他们的债务金额将在多久后相等?
答案:C
解释
Let the required time be x years. Then, 8000+8000*12/100*x= 9100+9100*10/100*x => 50x =1100 => x= 22 years
Q 40 - 6000 卢比在四年内以一定的利率累积到 7920 卢比。如果利率变为原来的 1.5 倍,那么五年后相同的本金的金额将是多少?
答案:B
解释
P = Rs. 6000, S.I = Rs. (7920-6000) = Rs. 1920, T= 4 years. R = (100*1920/6000*4) = 8% p.a. New rate = (1.5*8) % p.a. = 12% p.a. Now = Rs. 6000, R= 12% p.a. and T = 5 years. S.I = Rs. (6000*12/100*5) = Rs.3600 Amount = (6000+3600) = Rs. 9600.
答案:A
解释
given exp. = { 1+ 1/ (1+1/(4/3)} /11/7 = { 1+ 1/( 1+3/4)} /11/7 = [ 1+ 1/(7/4)]/11/7 = (1+4/7) /11/7 = 11/7 /11/7 = 1
答案:C
解释
given exp. = (3/2) / 1+ 1(/5/4) = (3/2)/ (1+4/5) = (3/2) /(9/5) = ( 3/2 * 5/9) = 5/6
答案:C
解释

答案:A
解释
given exp. = (79/14)/ 5+ 3/(3+5/3) = (79/14)/ 5+ 3/(14/3) = (79/14)/ 5+9/14 = (79/14)/(79/14) = 1
答案:B
解释
given exp. = 4 - [5/ {1+ 1/ 3+(1/ 9/4)}] = 4 - [ 5/{ 1+ 1/ (3+4/9)}] = 4 - [5 / {1+ 1/ (31/9)}] = 4 - 5/ (1+9/31) = 4 - 5/ (40/31) = 4- ( 5*31)/40 = 4- 31/8 = (32-31)/8 = 1/8
答案:C
解释
given exp. = 1 + 1/(1+ 1/(9/10)) =1 + 1/(19/10) =1 + 10/19 = 29/19
答案:A
解释
1/(1+ 1/ (1+1/x)) = 2 ⇒ 1/(1+x/(x+1)) = 2 ⇒ (x+1)/ (2x+1) = 2 ⇒ x+1= 4x+2 ⇒ 3x= -1 ⇒ x= -1/3
