Let the present age of Sonu is  7x years

Present age of Monu is 5x years

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

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

According to the question:

On cross multiplication, we get

Therefore present age of Sonu is 7x = 7 \(\times\) 5 = 35years

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