Question

five years ago A was there as aild as B and ten years later A shall be twice as old as B then tbe number presents age of A is??​

Answer 1

Answer

Correct option is

D

50,20

Let the age of A be a, and age of B be b

Now, a−5=3(b−5)

a=3b−10 (1)

After 10 years,

a+10=2(b+10)

a=2b+10 (2)

From 1 and 2,

3b−10=2b+10

b=20

And, a=2b+10=2×20+10=50 years

Thus, age of A = 50 years and age of B = 20 years.
