Question

23. A is two years older than b who is twice as old as c. If the total of the ages of a, band c be 27, then how old is b?

Answer 1

Answer:

Step-by-step explanation:

If A is 20 and twice the age of B, then B is 10. In 5 years B will be 15.

In algebra:

B*2=A=20

Divide both sides by 2:

B=10; therefore B+5=15
