Question

Alex, Stephen and Bridget share some sweets in the ratio 5:4:2. Alex gets 21 more sweets than Bridget. How many sweets are there altogether?

Answer 1

Answer:

Step-by-step explanation:

Let HCF of number of total sweets be x

So Alex owns 5x sweets

So Stephen owns 4x sweets

So Bridget owns 2x sweets

Alex has 21 more sweets than Bridget

So

5x = 2x + 21

5x-2x = 21

3x = 7

x = 7

So Alex has 5*7 = 35 sweets

So Stephen has 4*7 = 28 sweets

So Bridget has 2*7 = 14 sweets

So total number of Sweets is 35+28+14=77
