Ram is twice as old as Sita. If the sum of their ages is 45 years, how old is Sita?
Show answer & explanation
Correct answer: A
Explanation
Given:
Rama's age = twice Sita's age
Sum of their ages = 45 years
By the formula:
Total age = Rama's age + Sita's age
Let Sita's age = x years
Rama's age = 2x years
x + 2x = 45
3x = 45
x = 45 / 3
x = 15 years
