If a win carries an award of Rs. 150 and a loss carries of Rs. 100, what is the largest difference in prize money earned among the four?

Vishal Baghel

We get the following table of earnings:

Persons	Win Total	Average
P	36 * 150 + 14 * 100 = 6800	136
Q	34 * 150 + 21 * 100 = 7200	131
R	23 * 150 + 36 * 100 = 6850	116
S	30 * 150 + 30 * 100 = 6000	100

Now we can see that the largest difference

= Maximum – Minimum = Rs. 7500 – Rs. 6800

= Rs. 700
