答案:C
解释
Let z be the total number of voters. Votes polled = 90% of z Valid votes = (90% of (90% of z)) Therefore, 54% of [90% of (90% of z)] - 46% of [90% of (90% of z)] = 1620 → 8% of [90% of (90% of z)] = 1620 The number of voters enrolled were z = 25000
答案:C
解释
Let B receives Rs x ∴ A's Share = Rs 5x/4 C's Share = Rs 4x/3 According to question, x + 5x/4 + 4x/3 = 817 Or, (12x + 15x + 16x)/12 = 817 Or, x = (817*12)/43 = Rs 228 A's Share = 5x/4 = (5*228)/4= Rs 285
答案:A
解释
Let side =100m Area = 100*100=10000 m2 New area =125*125=15625 m2 Increase in area = 5625/10000*100=56.25%
答案:A

第 10 题 - A 公司的产量从 1994 年到 1995 年增长了 25%,从 1995 年到 1996 年又增长了 60%。从 1994 年到 1996 年,产量的总增长百分比是多少?
答案:D
解释
Production in 1996 = 160/100 * 125/100 * Production on 1994 = 20000/10000 * Production on 1994 = 2 * Production on 1994 ∴ Required % Increase = {(Production on 1996 - Production on 1994)/ Production on 1994}*100% Consider, Production on 1994 = x. Then, Production on 1996 = 2x. = (2x � x)/x * 100%= 100%
