Correct Answer - Option 4 : 29° C
Given:
The average temperature for Wednesday, Thursday and Friday was 30° C.
The average temperature for Thursday, Friday and Saturday was 32° C.
The temperature on Saturday was 35° C
Concept Used:
Average = Sum of observations/Number of observations
Calculation:
According to the question, we have
The temperature on (Wednesday + Thursday + Friday) = 30 × 3
⇒ 90° C
The temperature on (Thursday + Friday + Saturday) = 32 × 3
⇒ 96° C
Now,
The temperature on (Thursday + Friday) = 96° C - The temperature on Saturday
⇒ 96° C - 35° C
⇒ 61° C
Now,
The temperature on Wednesday = 90° C - The temperature on (Thursday + Friday)
⇒ 90° C - 61° C
⇒ 29° C
∴ The temperature on Wednesday is 29° C.
