Question

£750 is divided between Bridget, Caroline & Sarah so that Bridget gets twice as much as Caroline, and Caroline gets three times as much as Sarah. How much does Caroline get?

Answer 1

Answer: Caroline = 225

Explanation:

Let Sarah be x

Caroline will be 3x

Bridget will be 2(3x) = 6x

x + 3x + 6x = 750

10x = 750

x = 750 / 10 = 75

Caroline gets 3x = 3 * 75 = 225

Answer 2

£225

Explanation:

let x be the amount Sarah gets, then

Caroline gets 3x ( 3 times as much as Sarah )

Bridget gets 2 × 3x = 6x ( twice as much as Caroline )

Thus

x + 3x + 6x = 750, that is

10x = 750 ( divide both sides by 10 )

x = 75

Thus

Caroline gets 3x = 3 × 75 = £225
