Question

11. The sum of 5 numbers is 924, the average of the first two numbers is 201.5 and the average of the last two numbers is 196. What is the third number? 1) 133 2) 129 3) 122 4) Cannot be determined 5) None of these

Answer 1

2) 129
Let a+b+c+d+e = 924
a+b = 201.5 * 2 = 403
d+e = 196 * 2 = 392
c = 924 - (403+392)
c = 924 - 795
c = 129
