Question

The average of 3 and 7 will also be the average of the of the cubes of 3 and 7.

• A. True
• B. False

Answer 1

The correct option is B

False

The average of 3 and 7 is $\frac{3+7}{2}$ = 5

The cube of 5 is $5^3$ = 125

The cube of 3 is $3^3$ = 27

The cube of 7 is $7^3$ = 343

The average of 27 and 343 is $\frac{27+343}{2}$ = 185, which is not equal to cube of 5 i.e, 125

Hence the given statement is false
