Question

Five year ago Mukesh was 6 years older than his brother Suresh. If Mukesh is now thrice as old as Suresh find their present ages?

Answer 1

Answer:

Their present ages are 3 years and 9 years.

Step-by-step explanation:

Let Age of suresh five years ago = x

=>  Age of mukesh five years ago = x + 6

Present age of suresh = x + 5

Present age of Mukesh = x + 6 + 5 = x + 11

According to question, Mukesh is now thrice as old as Suresh

=> 3(x+5) = x + 11

=> 3x + 15 = x + 11

=> 3x - x = 11 - 15

=> 2x = -4

=> x = -2

Hence present age of suresh = x + 5 = -2 + 5 = 3

present age of Mukesh = x + 11 = -2 + 11 = 9

Hence their present ages are 3 years and 9 years.
