(a) 3 : 1

(b) 5: 2

(c) 5: 3

(d) 3: 2

SOLUTIONS:-

Sol 1. (c)

Sol 2. (d)

Sol 3. (b)

Sol 4. (a)

Sol 5. (d)

Sol 6. (c) Let initially milk and water in container B is 3x liter and x liter respectively

Now, 3x + 8/9 × 18 – x – 1/9 × 18 = 30

3x + 16 – x – 2 = 30, x = 8

So, Initial quantity is container B = 8 (3 + 1) = 32 Liter

Sol 7. (c) Total runs scored by team ? = 30 × 4.5 + 20 × 5.5 − 10 = 235

∴ Required answer = 235/50 = 4.7

Sol 8. (b) Total balls = 40 and Red balls = 18, So, Let green balls are x

Then, 18/40 × ?/39 = 3/26 ⇒ ? = 10

∴ No. of blue balls = 40 − 28 = 12

Sol 9. (d) Ratio of efficiency of A to B is 3: 2

Let In 8 days they complete = (3 + 2) × 8 = 40 units

So, total work = 40 × 12/5 units

Time taken by B alone to complete whole work = 40 × 12/5 ×2 = 48 days

Sol 10. (d) Investment ratio of A, B & C = (4000 × 6 + 3000 × 9): (5500 × 6 + 4000 × 9): 4? × 9

= 51000: 69000 : 36x = 8500 : 11500 : 6x

ATQ: 6?/(20000 + 6?) × 12250 = 2250, x=750

So, investment of C= Rs 3000

Sol 11. (d) Let cost price of each bread packet = Rs. a

So, marked price of each bread packet = 2.5a

And selling price of each bread packet = 2.5a × 60 100 = 1.5a

Given, 1.5a – ? = 30, a = 60 Rs.

New selling price = 2.5a × 5/8 = 1.5625?

Selling price of one bread packet = 1.5625 × 60 = 93.75

Required profit on selling 80 bread packets = (93.75 − 60) × 80 = 2700 Rs.

Sol 12. (b) Let present age of Sakshi = x

ATQ, ? = 5/4 (? − 6) ⇒ 4x = 5x – 30 ⇒ x= 30

Present age of her son = 30/5 = 6 years

Required ratio = 30 + 10/6 + 10 = 40/16 = 5/2
