Question

The average of four consecutive odd numbers p, q, r and s respectively (in increasing order) is 104. What is the sum of p & s?

Answer 1

Answer

(p + q + r + s)/4 = 104

p + q + r + s = 416 ---(1)

Since they are consecutive odd numbers:

q = p + 2

r = p + 4

s = p + 6

Put these values in (1):

p + p + 2 + p + 4 + p + 6 = 416

4p = 416 - 12

4p = 404

p = 101

s = p + 6 = 107

p + s = 101 + 107

= 208
