the following could be Vikram's age now and in 20 years?
(A) 12, 32
(B) 15, 35
(C) 18, 38
(D) 20, 40

Answer 1

Answer:

option c is correct 18, 38

Step-by-step explanation:

Vikram's present age is three times of his son

x = 3y _____(1)

And five years back his age was 4 times of his son

x - 5 = 4 (y - 5)

=> x - 5 = 4y - 20

=>3y - 5 = 4y - 20 [ x = 3y... from (1)]

=> -y = -15

=> y = 15

And again from (1)

x = 3×15

=> x = 38
