Question

Nitin is 4 years elder than his sister , if the sum of their ages is 20 years , then find the age of nitin

Answer 1

Answer: Age of Nitin= 12 years old

Step-by-step explanation:

Given that Nitin is 4 years older than her sister

Let her sister age be x

Nitins age = x+4

according to problem, sum of their ages is 20

so,

x+x+4=20

2x+4=20

2x= 20-4

2x= 16

x= 16/2

x= 8

Nitin sister age = 8 years

Nitins age= x+4

                = 8+4

                   = 12 years

∴ Nitins age is 12 years old
