Question

the ages of Sonu and monu are in the ratio 5.7 If 9years ago, the age of Sonu would have been twice the age of monu. find the ages
​

Answer 1

EXPLANATION.

• GIVEN

The age of sonu and monu are in the ratio

=> 5:7

9 years ago,the age of sonu would have

been twice the age of monu.

FIND THE AGES.

According to the question,

Let the age of sonu be = 5x

Let the age of monu be = 7x

=> 9 years ago, the age of sonu would

have been twice the age of monu.

=> Sonu age be = 5x - 9

=> monu age be = 7x - 9

=> 5x - 9 = 2 ( 7x - 9 )

=> 5x - 9 = 14x - 18

=> 9 = 9x

=> x = 1

Therefore,

sonu ages = 5x = 5 years.

monu ages = 7x = 7 years.

Answer 2

Answer:

Age of Sonu is 5 years and Monu is 7 years

Step-by-step explanation:

The ages of Sonu and monu are in the ratio 5:7.

Assume that the age of Sonu he 5x and Monu be 7x.

9 years ago, the age of Sonu would have been twice the age of Monu.

9 years ago:

• Age of Sonu = (5x - 9) years
• Age of Monu = (7x - 9) years

As per given condition,

→ 5x - 9 = 2(7x - 9)

→ 5x - 9 = 14x - 18

→ 14x - 5x = - 9 + 18

→ 9x = 9

→ x = 1

Hence, the present age of

• Sonu = 5x = 5(1) = 5 years
• Monu = 7x = 7(1) = 7 years
