**Solutions:**

S1. Ans.(c)

Sol.

Efficiency Mohit : Aman =1+1/5:1=6∶5

Given

5→42 days

∴ 6→(42×5)/6=35 days=x days

S2. Ans.(b)

Sol.

Hence

2M=3W=4Y

∴ (14M + 12W + 12Y) = 14 + 8 + 6 = 28 Men

Total Unit = 28 × 24

∴ 28 × 24 = x ×24

x=48

Total no. of men required for additional labour = 48 – 28 = 20 men

S4. Ans.(b)

Sol.

Let the total quantity of mixture be x ℓ.

∴ 3x=7(x-16) or x=28l

∴ quantity of milk = 12ℓ

S5. Ans.(b)

Sol.

Let selling price = x

C.P. for Vineet =((100-25))/100 x=0.75x

C.P. for Roshan =1/1.15 x

[x-0.75x]-[x-1/1.15 x]=275

x=2300

S6. Ans.(b)

Sol.

Let C’s share = Rs. x

∴ B’s share=75/100×x=3x/4

A’s share=5/4×3x/4=15x/16

∴15x/16+3x/4+x=6,192

⇒ x = Rs. 2,304

S7. Ans.(d)

Sol.

Let the original bill was Rs. P

∴7P/10+7P/10×18/100=4743-200

⇒(7×118P)/1000=4543

⇒P=5500

∴ Service charge paid by him=7/10×5500×8/100

=Rs.308

S8. Ans.(c)

Sol.

Let marked price = Rs. x

∴ 24×400/300=x×80/100

⇒ x = Rs. 40

S10. Ans.(a)

Sol.

Ratio of milk and water after 1st operation = 48 : 12 = 4 : 1

Final quantity of milk=(60 –12)×4/5

=38.4 l
