Question

years, Rahul will be one year less than twice as old as Nirmala will be
then. What is the age of Rahul today?
a. 12 years
b. 24 years
c. 36 years
d. 48 years
​

Answer 1

36 years

Let Nirmal present age= x

Rahul present age= 3x

After 13 years

So in both ages add 13

Now given in question that after 13 years ram age will be twice sita age minus 1 it means

2(x+13)-1=3x+13 ———————-(1)

2x+26–1=3x+13

2x+25=3x+13

3x-2x=25–13

x=12

So Nirmal 's present age =12

Rahul's present age =36
