Question

23. At present Hari is 3 years older than Ravi. If the age of Ravi is decreased by 10 years and that of Hari is
increased by 12 years, then the sum of their ages will be 29 years. Find the present age of Ravi and Hari.
​

Answer 1

Answer:

Let present age of Ravi be x.

so,present age of Hari=x+3

if,Ravi age=x-10

or Hari age=x+3+12

Then,

Ravi age + Hari age=29years

x-10+x+3+12=29years

2x+5=29years

2x=29-5

2x=24

or,x=12years

Hence,

Present age of Ravi=12years

Present age of Hari=15 years
