Question

Three numbers are chosen at random.

The middle number is 5 more than the smallest number.
The largest number is two times the smallest number.
The sum of the 3 numbers is 53.
What is the smallest number?

Answer 1

Answer:Smallest + Middle + Largest = 53

M= S + 2

L = 2S

Substitute M= S +2 and L = 2S into S + M + L =53

S + S + 2 + 2S = 53

4S + 2 = 53

4S/4 = 51/4

S = 12.75

M = 12.75 + 2

M = 14.75

L = 2 (12.75)

L = 25.5
