Question

Mac has $pounds$ $3$ more than Ken, but then Ken wins on the horses and trebles his money, so that he now has $pounds$ $2$ 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. Pounds $9$
• B. Pounds $11$
• C. Pounds $13$
• D. Pounds $15$

Answer 1

The correct option is C Pounds $13$

Let money with Ken $=x$. Then, money with Mac $=x+3$.
Now, $3x=(x+x+3)+2\iff x=5$.
Therefore Total money with Mac and Ken $=2x+3=13$.
