Question

A is twice as old as B was two years ago. If the difference in their ages be 2 years, find A's age
Select one
a. 8 years
b. 12 year
C. 15 years
d. 14 years
​

Answer 1

Answer:

A and B is the present age of them

their age before 2 years is C and D

now,C=A-2 and D=B-2

then, C=2D

A-2=2(B-2)

A-2=2B-4

1. A-2B= -2

2. A-B=2

subtract 1 and 2

(A-2B= -2) - (A-B=2)

B=4

A-B=2

A-4=2

A=6
