Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Rs 188.
We know that,
Average = Sum of observations/Number of observations
Now,
Total income of the worker in this week = 7 × 180 = 1260
Total income from Monday to Saturday = 115 + 212 + 170 + 165 + 185 + 255 = 1072
Income on Sunday = 1260 - 1072 = 188
