Question 769644
7 * 1400 = 9800
8 * 1600 = 12800
    Total = 22600
For average, divide by total number of workers (15)
rs 22600/15 = rs 1506.67.
..................
If avg score of 10 players = 42
then total = 10 * 42 = 420
If each player makes 12 extra runs = 120
420 + 120 = 540
540/10 = 54 (The new average)
Hope this helps.
