Question

The sum of three numbers is 83. The first number is 8 more than the second. The third number is 3 times the second. What are the numbers?

Answer 1

23, 15 and 45

Explanation:

a+b+c = 83

a = b + 8

c = 3*b

(b+8) + b + 3*b = 83

5*b + 8 = 83

5*b = 75

b = 15

a = b + 8 = 15 + 8 = 23

c = 3*b = 3*15 = 45

Verification

a+b+c = 23 + 15 + 45 = 83; correct
