Sum of present ages of A and B is 60 years. 5 years hence, their ages will be in the ratio 3:4. Find A’s present age.
a) 25 years
b) 30 years
c) 35 years
d) 40 years
e) None of these
Sum of their present ages = 60 years
sum of their ages, 5 years hence = 60 + (5 × 2) = 70 years.
after 5 years, ratio of ages of A and B will be 3 : 4.
A’s age after 5 years = (3/7) × 70 = 30 years
A’s present age = 30 – 5 = 25 years
Answer: a)
