Question
The average of a set of 's' numbers is 60. If 150 is
added to the set, then the average of the set becomes 60.5. Find the value of '4 X (s - 10)'.Solution
Sum of all 's' numbers = 60s
ATQ:
(60s + 150) / (s + 1) = 60.5
Multiplying both sides by (s + 1):
60s + 150 = 60.5(s + 1)
60s + 150 = 60.5s + 60.5
150 - 60.5 = 60.5s - 60s
89.5 = 0.5s
s = 179
4 X (s - 10):
4 X (179 - 10) = 4 X 169 = 676
