Question

Rahul is 3 years older than Raj. if the sum of their ages is 27 years. what are their present ages​

Answer 1

Answer:

Let Raj be a, and Rahul be b.

a = 5b ….. (eqn 1)

a + b = 18 …… (eqn 2)

Putting eqn 1 in 2, we get,

5b + b = 18

or, 6b = 18

Hence, b = 3

Now,

a + 3 = 18

or, a = 15

Thus, Raj is 15 years old, and Rahul is 3 years old.

Step-by-step explanation:

Let Rahul's age be X. Then, Raj's age is 5X.

According to the question, X+5X=18. Solving for X, we get, 6X=18. X=3.

Thus Rahul is 3 years old while Raj is 15 years old.
