20. 

Mac has £ 3 more than Ken, but then Ken wins on the horses and trebles his money, so that he now has £ 2 more than the original amount of money that the two boys had between them. How much money did Mac and Ken have between them before Ken's win ?

[A]. £ 9
[B]. £ 11
[C]. £ 13
[D]. £ 15

Answer: Option C

Explanation:

Let money with Ken = x. Then, money with Mac = x + £ 3.

Now, 3x = (x + x + £ 3) + £ 2 x = £ 5.

Therefore Total money with Mac and Ken = 2x + £ 3 = £ 13.

Treble means three times the amount thus we will equate the new amount of money shared with, 3x.

Ken amount = x and mac amount = y.

Initially, mac = 3+ken.

Therefore y = 3+x.

Then ken win,

Now, 3x = (initial amount of mac and ken together)+5.

Initial amount of ken is x.

Mac is x+3.

Therefore 3x = (x+x+3)+2.

3x = 2x+5.

x = 5.

Therefore y = x+3 = 8.

Then initially total amount of both (x+y) = 5+8 = 13.
