Question

Alex, Susan and Amy shared 66 watermelons. The number of watermelons owned by Alex is two times the number of watermelons owned by Susan, while Amy has 6 more than Susan. Find the ratio of the number of watermelons owned by Susan to the number of watermelons owned by amy.​

Answer 1

5:7

Explanation:

First you have to find the watermelons owned by the three of them.

Let's take Susan as 'x'

According to the question:

1. Alex has twice the watermelons as Susan -> 2x

2. Amy has 6 more watermelons than Susan -> x+6

The sum of the watermelons is 66

SO,

x + 2x + x + 6 = 66

4x = 60

x = 15

Susan has 15

Alex has 30

and Amy has 21

Now we do the ratio:

Susan : Amy

15 : 21

5 : 7
