(2) Expenditure on medical facilities for students is Rs. 4·6 lac

(3) Difference between the expenditure on research work and medical facilities for student is Rs. 60,000

(4) All are true

(5) None of these

Answer & Explanation

**1. (2)**

Required sum = (8 +24 + 6)% of 60 = 22.8 lac

**2. (2)**

Required difference = (15 – 10)% of 60 = 3 lac.

**3. (5)**

Required ratio = 8 : 6 = 4 : 3

**4. (2)**

The expenditure after the decrease = 93% of 24% of 60 = 13.392 lac = 1339200.

**5. (3)**

In option (1), the ratio is 1 : 3 not 3 : 1, so (1) is not true.

In option (2), the expenditure on medical facilities = 7% of 60 = 4.2 lacs, hence (2) is not true.

In option (3) the difference = (8 – 7) % of 60 lac = 60000. Hence (3) is true
