Question 1043912
The sum of four numbers is 720. One of the numbers, p, is 25% more than the sum of the other three numbers. What is the value of p?
----------
Call them p, q, r & s
p + q + r + s = 720
p = 1.25*(q + r + s)
---
1.25*(q + r + s) + q + r + s = 720
2.25*(q + r + s) = 720
q + r + s = 320
p = 400
