Question

Age of a is 20 years less than that of b. If age of a is 40% of their combined age, what are the ages of a and b?

Answer 1

Answer:

40 & 60 Years

Step-by-step explanation:

Age of a = a

Age of b = a+20

Combined age = a + a+20 = 2a + 20

A = 40% of combined age

a = (40/100)(2a + 20)

a = 0.8a + 8

0.2a = 8

a = 8/0.2

a = 40

b = 40 + 20 = 60
