The average temperature on Wednesday, Thursday and Friday was 25°C. The average temperature on Thursday, Friday and Saturday was 24°C. If the temperature on Saturday was 27°C what was the temperature on Wednesday?

A 24°C

B 21°C

C 27°C

D 30°C

Solution

Correct Answer: Option D

Thurs + Fri + Sat = 24 * 3 = 72

Sat = 27

So, Thurs + Fri = 72 - 27 = 45

Again,

Wed + Thurs + Fri = 25 * 3 = 75

or, Wed = 75 - (Thurs + Fri)

or Wed = 75 - 45

= 30
