Students of Primary, Middle, Secondary and Sr. Secondary classes collected donation for a Relief Fund as shown in the pie chart. If the donation collected from Middle classes was ₹6,750, then what would be the total amount of money collected by Secondary and Sr. Secondary classes?
Answer & explanation
Correct answer: option 2
Donation from middle class = 30% of donation from all classes
ATQ,
30% of donation from all classes= 6750
Donation from all classes = \(\frac{6750 }{30}\) × 100 = 22500
Total amount of money collected by Secondary and Sr. Secondary classes
= \(\frac{27 + 25 }{100}\) × 22500
= \(\frac{52 }{100}\) × 22500
= Rs. 11700
