**Solutions:**

S1. Ans.(c)

Sol.

Let he borrowed Rs P from Jayant

(P×8×4)/100+(P×10×6)/100+(P×5×12)/100=12,160

⇒ P = Rs 8000

S4. Ans.(a)

Sol. A number will be divisible by 5 if it has either 5 or 0 at its end.

∴ Total numbers formed which are divisible by 5 = (5 × 4 × 3 × 2) + (4 × 4 × 3 × 2)

= 216

S5. Ans.(c)

Sol.

Let total wine = 100 li

∴ alcohol = 40 li, water 60 li

Let x amount is taken out

∴ new quantity of alcohol =2/5×(100-x)+x/4

⇒40-2x/5+x/4=30/100×100

⇒3x/20=10

⇒x=200/3

∴ Required answer = 2/3

S6. Ans.(c)

Sol.

Ratio of efficiencies of Ajit, Baljit and Diljet respectively

=3/2:1∶4/5

= 15 : 10 : 8

∴ Time taken by Baljit

=33/10×20

= 66 days

S7. Ans.(d)

Sol. 10/3×18/5 = 12 km/h

Sol. 10/3×18/5 = 12 km/h

S9. Ans.(b)

Sol. reduction in consumption

=15/((100+15) )×100=15/115×100

=300/23=13 1/23%

S10. Ans.(b)

Sol. Required Reduction in price

=20/((100+20) )×100=20/120×100

= 16 2/3%
