Question

12. A is now 19 years older than B. In 10 years, A
will be twice as old as B. Find B's present age.
(a) 7 years
(b) 8 years
(c) 9 years
(d) 10 years​

Answer 1

Answer:

Answer is (c) 9 years

Step-by-step explanation:

Let B's age be x years

Let A's age be (x+19) years

Age of A after 10 years = (x+19+10)

                                       = (x+29) years

Age of B after 10 years = (x+10) years

According to the problem (ATP),

=> x+29 = 2(x+10)

=> x+29 = 2x+20

=> x - 2x = 20 - 29

=> -x = -9

=> x = 9

Hence, B's age is 9 years
