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
