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
