Answer 2

Answer: 27

Step-by-step explanation:

Let the ages of A and B 10 yr before were 13x yr and 17x yr, respectively.

Then, present age of A = 13x + 10 and present age of B = 17x + 10

According to the question,

13x+10+1717x+10+17=1011

13x+2717x+27=1011

Hence, present age of B = 17 x 1 + 10 = 27yr
