Question

Ron is five years older than twice his cousins Pat's age. The sum of their ages is less than 35. What is the minimum age Pat can be?

A.) 7
B.) 8
C.) 9
D.) 10

Answer 1

r = 2p + 5
r + p < 35

2p + 5 + p < 35
3p + 5 < 35
3p < 35 - 5
3p < 30
p < 30/3
p < 10.....Pat has to be less then 10


minimum age : 7
maximum age : 9
