The average of 7 numbers is 42. The last two numbers is 37 and 32. Find the average of the five numbers

Question

Average of 7 numbers = 42

Last 2 numbers 37 and 32

Answer 1

The last two numbers ARE 37 & 32.

 

42 = (1/7)(32+37 + sum of five numbers)

294 = 69 + sum of five numbers

225 = sum of five numbers

therefore average of five numbers = 225/5 = 45
