Question

5. 1) 5 A is as much younger than B as he is older than C. If the sum of B's age and C's age is 40 years. Find the age of A?
2) 25 yrs 1) 20 yrs 3) 30 yrs 4) 24 yrs 5) 22 yrs
​

Answer 1

Step-by-step explanation:

Correct 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 some of the ages of B and C are 40 years. So, A = (B + C) /2 = 40/2 = 20 Years
