Question

In a quick, positive marks are given for correct answer and negative marks are given for incorrect answer. If Jacks scores in five successive round were 25,-5, -10, 15 and 10 , what was his total at the end?

Answer 1

The exact half way point would be 4.5 /9, which is very hard to deal with.

In order to make this simpler to understand. Let's do this the easy way.

Change 4/9 to 8 /18.

(Do this by multiplying the top and bottom of the fraction by 2.)

Change 5/9 to 10/18.

(Do this by multiplying the top and bottom of the fraction by 2.)

Now we want the midpoint of 8/18 and 10/18. That would be 9/18.

This can be reduced to 1/2.

Answer 2

His total score = 25-5-10+15+10= 35

so his total score at the end was 35
