ANSWERS WITH EXPLANATION:

Solutions (1-5)

Village	Total number of people	Number of men	Number of women	Number of children
L	1240	434	558	248
M	2140	963	642	535
N	1450	725	435	290
O	1680	1092	336	252
P	2060	824	824	412
Q	1990	796	995	199
Total	10560	4834	3790	1936

1. (3)

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 after the decrease = 93% of 24% of 60 = 13.392 lac = 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
