Question

lakhan is 15 years older than his brother mohan after 3years lakhan will be 8times as old as mohan 3years ago find their present age​

Answer 1

Answer Present age of lakhan is 21 years

Present age of Mohan is 5 years

Step-by-step explanation:

Let the present age of Mohan be x then

the present age of lakhan will be (15+x)

three years ago Mohan's age was x-3

And after 3 years from now lakhan's age will be (x+15+3)

as given that lakhan's age after 3 years from now will be equal to 8 times of Mohan's age 3 years ago.

x+15+3 = 8(x-3)

x+18 = 8x- 24

x-8x = -24-18

-7x = -42

x=6

So as assumed Mohan's present is x= 6 years

and lakhan's present age is x +15 = 21 years
