In Class 12, twenty five per cent of the vegetarians are male. What is the difference between the number of female vegetarians and male non-vegetarians?
Answer & solution
- A
less than 8
- B
10
- C
12
- D
14
16
Vegetarian Males in Class 12 = 0.25 × 32 = 8
∴ Non-vegetarian Males in class 12 = 48 – 8 = 40
∴ Vegetarian females in class 12 = Vegetarians in class 12 – Male vegetarians in class 12
= 32 – 8 = 24 (We derived the number of vegetarians in the class in the previous question)
∴ Required difference = 40 – 24 = 16
Hence, option (e).
