1. (3) According  to the table.

2. (4)
Required ratio = (558 + 824) : (434 + 824) = 691 : 629

3. (5)
Required sum = 995 + 199 = 1194.

4. (1)
Required percentage = 1680/10560 * 100 = 16%.

5. (2)
Required sum = 535 + 290 = 825


Solutions (6-10)
6. (2)
Required sum = (8 +24 + 6)% of 60 = 22.8 lac

7. (2)
Required difference = (15 – 10)% of 60 = 3 lac.

8. (5)
Required ratio = 8 : 6 = 4 : 3

9. (2) The expenditure of overhead & projector for PHD= 24% of 60lakh= 14.40lakhs.
According to the qs. 7% of 14.40 = 1.008 lakhs

The Expenditure after the decrease = 14.40 – 1.008 = 13.392 = 1339200

10. (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.
