Question 64

The average temperature of Tuesday, Wednesday and Thursday was $$45^\circ C$$. The average temperature of Wednesday, Thursday and Friday was $$46^\circ C$$. If the temperature on Friday was $$47^\circ C$$, what was the temperature on Tuesday?

Solution

Sum of temperatures on Wednesday, Thursday and Friday= 46*3 = 138

The temperature on friday= 47

So, the sum of temperatures on Wednesday and Thursday= 138-47 = 91

Sum of temperatures on Tuesday, Wednesday and Thursday= 45*3 = 135

The temperature on Tuesday= 135-91= 44
