7-n = 5
Number of holidays = 2
Total weight of 50 boys = 45 X 50 = 2250
Average weight of 49 boys = 44.9
Total weight of 49 boys = 44.9 X 49 = 2200.1
Weight of boy who left the class=2250?2200.1=49.9
Total runs scored by team
Let the average expenditure of 19 people be x
?19x = 13 X 79 + 6 X (x+4)?19x = 13 X 79 + 6x +24
?x = 80.84
So, total money spent by them = 1536.07
