Question

Alex, Stephen and Bridget share some sweets in the ratio 1:5:3. Alex gets 10 sweets. How many did Bridget get?

Answer 1

Answer:

30 sweets

Step-by-step explanation:

Ratio in which they get the sweets = 1:5:3

Sweets received by Alex = 10

Let there be x sweets

sum of ratios = 1 + 5 + 3 = 9

therefore,

$\frac{1}{9} * x = 10\\x = 10*9 = 90$

therefore there are 90 sweets

sweets received by Bridget:

$Sweets \ received \ by \ Bridget \ = \frac{3}{9} * x = \frac{3}{9} * 90\\= 3 * 10 = 30$

therefore Bridget received 30 sweets
