1). 30, 352). 30, 363). 35, 364). 36, 38

Answer»

Given data -

An average of 5 numbers = 40

Total summation of numbers = average × 5

Total summation of numbers = 40 × 5

Total summation of numbers = 200

When 2 numbers are being excluded the average of REMAINING 3 numbers becomes 45.

Total of remaining 3 numbers = 45 × 3

Total of remaining 3 numbers = 135

From above we can see sum of excluded numbers = 200 - 135 = 65

Only option of numbers which add up to 65 is 30, 35

∴ Excluded numbers are 30 & 35.
