Q.

One year ago, Mrs Promila was four times as old as her daughter Swati. Six years hence, Mrs Promilas age will exceed her daugther’s age by 9 years. The ratio of the present ages of Promila and her daughter is ?                         [C.B.I 1993]


A. 9:2 B. 12:5
C. 11:3 D. 13:4

Answer: Option D
Explaination:

 


Let Swatis age 1 year ago = x.


Then, Promilas age 1 year ago = 4x.

(4x+6) - (x+6) = 9 or x = 3.

Present age of Promila = (12 + 1) years = 13 years.

Present age of Swati = (3+ 1) years =4 years.

Ratio of their ages = 13 : 4.
