Q:

A) 33 | B) 34 |

C) 39 | D) 29 |

Answer & Explanation
Answer: A) 33

Explanation:

Explanation:

Let the fifth number be x.

The average of the first four numbers = 3x

Sum of all the first four numbers = 3x = 12x

The average of all the five numbers = 85.8

Sum of all the five numbers = 85.8 5 = 429

Sum of all the first four numbers + 5th number = 429

12x + x = 429

x = 429/13 = 33

The 5th number is 33.
