Question

a man's present age is 5 times his son's age 7 years hence man's age will be thrice his son's age find their present age how one should care their parents in old age??

Answer 1

Let the present age of son be a

Present age of father = 5a

According to question,

( 5a + 7) = 3( a + 7)

=> 5a + 7 = 3a + 21

=> 5a - 3a = 21 - 7

=> 2a = 14

=> a = 7

Present age of son = 7 years

Present age of father = 35 years
