**Solutions:**

S1. Ans.(d)

Sol. x+y-xy/100

10+30-(30 × 10)/100

40 – 3

= 37%

S2. Ans.(b)

Sol. Increase% =((P + D) × 100)/(100-D)

20=((P+8) × 100)/92

92 = 5P + 40

52 = 5P

P = 10.4%

S3. Ans.(c)

Sol. 39=x×97.5/100

975x = 39000

x=39000/975

x = 40

S4. Ans.(b)

Sol. 810=1000×90/100×(100-D)/100

90 = 100 – D

D = 10%

S5. Ans.(a)

Sol. 25=(P+16)×100)/84

21 = P + 16

P = 5%

S6. Ans.(d)

Sol. 20=(P+10)×100)/90

90 = 5P + 50

5P = 40

P = 8%

S7. Ans.(d)

Sol. Skilled : Half Skilled : Unskilled

4 : 3 : 2

28 : 24 : 20

7 : 6 : 5

Skilled = 369 × 7/18

= 143.5

S10. Ans.(d)

Sol. Jaya = 10 × 3/2

= 15 unit

= 15 × 3/5

= 9 days
