Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2.
School X: Semester fee (in lakhs) = 43 and Donation (in lakhs) = 14
3 × 14 = 42 < 43
School Y: Semester fee (in lakhs) = 56 and Donation (in lakhs) = 17
3 × 17 = 51 < 56
School Z: Semester fee (in lakhs) = 39 and Donation (in lakhs) = 14
3 × 14 = 42 > 39
School U: Semester fee (in lakhs) = 89 and Donation (in lakhs) = 50
3 × 50 = 150 > 89
School V: Semester fee (in lakhs) = 59 and Donation (in lakhs) = 16
3 × 16 = 48 < 59
Therefore, the income by semester fee is less than three times of donation in 2 schools.
