Eight years ago, Pranathi�s age was equal to the sum of the present ages of her one son and one daughter. Five years hence, the respective ratio between the ages of her daughter and her son that time will be 7:6. If Pranathi�s husband is 7 years elder to her and his present age is three times the present age of their son, what is the present age of the daughter?
A. 19 years
B. 27 years
C. 15 years
D. 23 years
Ans: D. 23 years
Explanation:
P � 8 = S + D �(1)
6D + 30 = 7S + 35 �(2)
H = 7 + P
H = 3S
3S = 7 + P �-(3)
Solving equation (1),(2) and (3) D = 23
Therefore, the present age of the daughter is 23 years -
Shas married 8 years ago. Today her age is 9/7 times to that time of marriage. At present his son�s age is 1/6th of her age. What was her son�s age 3 years ago?
A. 4 yr
B. 2 yr
C. 3 yr
D. 5 yr
Ans: B. 2 yr
Explanation:
Let us assume that Shas�s age 8 years ago = x
Present age = x + 8
x + 8 = 9/7 x
7(x + 8)= 9x
x = 28; 28 + 8 = 36
Son�s age = 1/6 * 36 = 6
Son�s age 4 years ago = 6-4 =2 -
