A : B : C = 8 : 14 : 22 = 12 : 21 : 33 B : C : D = 21 : 33 : 44 Therefore, A : B : C : D = 12 : 21 : 33 : 44
答案:D
解释
Let the present ages of Seema and Rupa be x years and y years respectively. According to question, (y - 6) = 2(x - 6) Or, y - 6 = 2x - 12 Or, 2x - y = 6 ...(i) Similarly, (x + 4)/(y + 4) = 3/5 Or, 5x + 20 = 3y + 12 Or, 5x - 3y = - 8 ... (ii) From equ (i) and equ (ii), 6x - 3y = 18 5x - 3y = -8 We get, x = 26 years and y = 46 years
答案:A
解释
Let the present age of the son be x year. Then , present age of the man = 5x year ∴ (5x-5 = 10 (x-5) ⇒ 5x= 45 ⇒ x = 9 Age at the present time of the father is = (5*9) = 45 year
答案:A
