1. 1
(6x + 6)/(7x + 6) = 15/17
2. 3
1 * b = Area
1 * 1 = 1
After changes, 1.2 * 0.9 = 1.08
There is 8% increase in the area.
3. 4
Loss% = (47000 - 45800)/47000 * 100
4. 5
Req no. of days - 1/ (1/8 - 1/12)
5. 2
Req CI = 10000 * (1.2)^4 - 10000
10000 * (2.0736 - 1)
6. 1
(20736/12000) = (1 + R/100)^3
7. 2
Required = 7P7
8. 4
No. of valid votes other candidate got = (100 - 72)/100 * (8200 - 8200*25/100)

Answers :
Solution
1.(1) ×1/2,×1,×3/2……..
2.(3) 2^3+1,3^3+1,......
3.(1) Two series mixed ,one prime no series,so next no will be 13
4.(2)
5.(2)Let A efficiency=2 & B efficiency=1
Total work=(2+1)*18=54
So A can do a work in 18 days
6.(2) 1/3:1/6 = 2:1
7.(2)
8.(3) 100 % = 360
30 % = 360/100*30 = 108
9.(1) 70 % of 50 = 35 kg
10.(2) 1 - (1/6 +1/10) = 11/15
