of A.
(5) None of these
(1) 20 years
(2) 25 yerars
(3) 30 years
(4) 27 year​

Answer 1

Answer:

(1) 20 years

Step-by-step explanation:

Age of C < Age of A < Age of B

From question,

A = C + x ....(i)

B = A + x ....(ii)

From equation (i) and (ii)

A - B = C - A

⇒ 2A = B + C

⇒ A = (B + C) / 2

Given that sum of the ages of B and C is 40 years.

So, A = (B + C) / 2 = 40/2 = 20 Years
