Question

Sonu is 7 year elder than his brother monu. The sum of their ages is 25. Find the age of both sonu and monu

Answer 1

Answer:

Sonu's Age = 16 years

Monu's Age = 9 years

Step-by-step explanation:

Let Monu's age be x

(x-7)+x=25

x-7+x=25

2x-7=25

2x=25+7

2x=32

Therefore,x = 32/2=16

which means,

Monu's Age=16 years

Sonu's Age=(16-7)=9 years

Answer 2

Answer: Age of Sonu = 16 years

Age of Monu = 9 years

Step-by-step explanation:

Let the age of sonu be x

And that of Monu be y.

A/c to 1st condition

x = 7 + y ......(1)

A/c to 2nd condition

x + y = 25 ........(2)

Put equation (1) in equation (2)

7 + y + y = 25

7 + 2y = 25

2y = 25 - 7

2y = 18

y = 9

Put y = 9 in equation (1)

x = 7 + 9

x = 16
