Question
The average monthly fee for 30 students in a workshop is
Rs. 10,000. After an increase, the new monthly average fee for each student is Rs. (10000 + X). If the total fees for all students post-increase is Rs. 3,30,000, find the value of (4X + 10% of X).Solution
ATQ, Initial total fees for 30 students = 30 X 10000 = 3,00,000 New total fees for all 30 students = Rs. 3,30,000 Total fee increase = 330000 - 300000 = Rs. 30,000 So, X = (30000/30) = 1000 So, 4X + 10% of X = 4 X 1000 + 0.10 X 1000 = 4000 + 100 = 4100
