present age of B?

2.49​

Answer 1

Answer:

49 years

Step-by-step explanation:

3 years ago,

(A+B+C) ÷ 3 = 32

A+B+C = 96 years

Current age total of A,B,C

= 96  + 3 + 3 + 3= 105 years

After 4 years from now,

A+B+C = 105 + 4 + 4 + 4

A+B+C = 117 years   (eqn.1)

(A+C)÷2 = 32    (given)

A+C = 64 years

Substitute this value in eqn. 1

64+B = 117

B = 53

B's age after 4 years will be 53 years,

So, current age of B = 53-4

= 49 years
