The average of five numbers is 62. The average of the first two numbers is 48 and that of the last two numbers is 52. What is the third number?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 110.
Sum of 5 numbers = 62 × 5 = 310
Sum of first 2 numbers = 48 × 2 = 96
Sum of last 2 numbers = 52 × 2 = 104
Sum of first 2 and last 2 numbers = 96 + 104 = 200
Third number = 310 - 200 = 110
