(b) Krishna ,660

(c) Ganesh .660

(d) Ram and Ganesh ,660

(e) None of these

**Answers:**

1. (d)

Male: Female

4x : 3x

3y : 2y

5z : 4z

Since 2y = 4z

(4x + 3x) + (3y + 2y) + (5z + 4z) = 33

7x + 19z = 33

x = 2

i.e. No of Female children in A = 3*2 = 6

3.(c)

After 1st process milk & water = 9 : 1

After 2nd process milk left

= 800 * 9/10 = 720

So, Milk & Water = 720:280 = 18:7

After 3rd process milk left = 600*18/25 = 432

4. (b)

Ratio of capital = 54000 : 36000 : 7200

= 15 : 10 : 2

Profit of Mohan = 13500 * 2/27 = 1000

5. (c)

Ratio of their profit = 540*6 : 360*15 : 720*30

= 3 : 4 : 2

Profit of Ram = 13500*3/9 = 4500

6. (a)

Let B’s Capital = x, A’s Capital = x+20000

& C’s Capital = x-4000

According to question

x+(x+20000)+(x-4000) = 136000

x = 40,000

A = 60,000, B = 40,000, C = 36,000

A:B:C = 15:10:9

A’s share = (15*51000)/34

= 22,500

7. (a)

5A = 4B = 7C = K

A:B:C = 28 : 35 : 20

8. (d)

1 cow = 3 calves

Ratio of cattle’s of A, B & C

(4*3+3)*5 : (5*3+4)*3 : (6*3+5)*2

= 15 : 19 : 23

Ratio of their rent = 15*5 : 19*3 : 23*2

75 : 57 : 46

Rent of B = 2470*57/178 = 855

9. (b)

Ratio of their capital

(500 * 12) : (3000*4 + 4000*8) + (7000*8 + 3000*4)

= 15 : 11 : 17

Jai’s Share = 34400 * 11/43 = 8800

10. (a)

Capital ratio

(5*3 + 3*6) : (4*4 + 3*5) : (3*4 + 4*5)

= 33 : 31 : 32

Ram Share = 1920*33/96 = 660
