No student brought an amount between 170 and 260 and the highest amount that anyone brought is Rs. 300. What is the average amount with students who belong to C? [Round off your answer to the nearest integer.]
Explanation:
Consider the solution to first question of this set.
Now, since no student brought an amount between 170 and 260 and the highest amount that anyone brought is Rs. 300, we can have the following amounts (written in green) for each category in C.
∴ Average = (50 × 72 + 100 × 48 + 300 × 8 + 150 × 12) / (72 + 48 + 8 + 12) = 90.
Hence, 90.
