Chandra is 10 years younger than Chandrika. 5 years later Chandrika will be twice as old as Chandra. Find Chandrika's present age.

Correct option is C

Given:

Chandra is 10 years younger than Chandrika.

5 years later Chandrika will be twice as old as Chandra.

Solution:

Let Chandrika's present age = $$x$$​​

Chandra's present age will then be =$$x-10$$

Five years later:

Chandrika's age will be = $$x+5$$​​

Chandra's age will be = ($$x-10$$) + 5 = $$x-5$$

According to question:

=> $$x+5$$ = 2($$x-5$$)

=> $$x+5$$​ = $$2x-10$$​      

=> $$x$$ = 15 years   

Thus the correct answer is (C)
