(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
