Average of 11 numbers is 32. If the average of first six numbers is 26 and the average of last six numbers is 36 then what is the value of the sixth number?
Answer & explanation
Correct answer: option 1
Sum of 11 numbers = 11 × 32 = 352
Average of first six numbers = 6 × 26 = 156
Average of Last six numbers = 6 × 36 = 216
Sixth number = ( 216 + 156 ) - 352 = 20
