Answer 1

Answer:

$\qquad\qquad\underline{\textsf{\textbf{ \color{magenta}{AnSwEr} }}}$

Let the present age of Sonu be 7x years

Present age of Monu be 5x years

➙ Sonu’s age After 10 years = (7x + 10) years

➙ Monu’s age after 10 years = (5x + 10) years

So, according to the question or ATQ :-

➔ (7x + 10) / (5x + 10) = 9/7

By using cross-multiplication we get,

➔ 7(7x + 10) = 9(5x + 10)

➔ 49x + 70 = 45x + 90

➔ 49x – 45x = 90 – 70

➔ 4x = 20

➔ x = 20/4

➔ x = 5

∴ Present age of Sonu is 7x = 7(5) = 35years

Present age of Monu is 5x = 5(5) = 25years
