Question

ramesh and mahesh's ageis 5:7 after 4 yers age 3:4
​

Answer 1

Explanation:

let present age of of ramesh and mahesh be x

then,

(5x+4)/(7x+4)=3/4

Answer 2

let the common multiple be x.

age of ramesh is 5x and age of mahesh is 7x.

from given condition.

$\frac{5x + 4}{7x + 4} = \frac{3}{4}$

$4(5x + 4) = 3(7x + 4)$

$20x + 16 = 21x + 12$

$21x - 20x = 16- 12$

$x = 4$

so,

age of ramesh =5x = 5×4=20 years.

age of mahesh =7x = 7×4=28 years.
