Q 1 - Rs.11256 is divided among X,Yand Z so that X may receive 1/3 as much as Y and Z together receive Y receives 1/5 of what X and Z together receive. The share of X is more than that of Y by:

### Answer : A

**Explanation**

X = 1/3(Y+Z) => Y+Z = 3X =>X+Y+Z = 11256 => 4X = 11256 => X = 2814 Again, Y = 1/5(X+Z) => X+Z = 5Y => 6Y = 11256 =>Y = 1876 Then X's share is more than that of Y by Rs. (2814-1876) =938

### Answer : A

**Explanation**

18: x=x: 18 =>18/x=x/18=>x=18

### Answer : D

**Explanation**

0.6*A = 0.09 *B A/B =0.09/0.6 = 0.09/0.60 = 9/60 =3/20 ∴A:B = 3:20

### Answer : D

**Explanation**

X * 17.5 =7*22.5 => X= 7*22.5/17.5 = 7*225/175 =9.

Q 5 - In a school, the proportion of young men and young ladies is 4:5 . at the point when 100 young lady leaves the school , the proportion gets to be 6:7 . What are number of young men are there in the school?

### Answer : B

**Explanation**

Let the number of boys and girls be 4x and 5x respectively. Then,4x/5x-100=6/7?28x=30x-600 =>2x=600 => x=300. Number of boys=(4*300)=1200.

Q 6 - What must be added to each term of the extent 7:13 so that the extent gets the chance to be 2:3 ?

### Answer : D

**Explanation**

Let the number to be added be X. Then, 7+x/13+x= 2/3 => 3(7+X)=2(13+x) => X= (26-21)= 5 ∴ number to be added = 5.

Q 7 - A portion bears the same proportion to 1/27 as 3/7 does to 5/9, the part is :

### Answer : B

**Explanation**

Let the fraction be X. Then, X:1/27 = 3/7 :5/9 => x *5/9= 1/27 *3/7 = 1/63 => x=(1/63*9/5) = 1/35 Required fraction =1/35

Q 8 - The whole of three square of three no. which are in the proportion 2:3:4 is 725. What are three numbers?

### Answer : A

**Explanation**

Let the numbers be 2x, 3x and 4x. Then, 4x^{2}+9x^{2}+16x^{2}= 725 => 29x^{2}=725 x^{2}= 25 => x =5 ∴ The numbers are 10, 15, 20 .

Q 9 - Income of A ,B and C are in the proportion 7:9:12 and their consumption are in the proportion 8:9:15 . On the off chance that A sparing is 1/4 of his wage, then the proportion of sparing of A,B and C is:

### Answer : A

**Explanation**

Let the incomes of A, B and C be 7x, 9x and 12 x and their expenditures be Rs 8y,Rs 9y and Rs 15y respectively. Then their savings are Rs(7x -8y), Rs(9x-9y) and Rs (12x-15y). ∴7x-8y=1/4*7x =>28x-32y=7x =>21x=32y. Ratio of saving=(7x-8y):(9x-9y):(12x-15y) = (7*32/21y-8y):(9*32/21y-9y):(12*32/21y-15y) = (32y-24y/3):(96y-63y/7):(128y-105y/7) = 8y/3:33y/7:23y/7=56:99:69.

Q 10 - Rs 3068 are circulated among A,B and C such that on diminishing Their shares by Rs 10,Rs 14 and Rs 20 individually, the parity cash would be isolated among then in the proportion 5:6:7. at that point ,B offer is:

### Answer : B

**Explanation**

Money in the ration 5:6:7 is Rs (3068 -44) =Rs 3024. ∴B share =Rs{(3024*6/18)+14}=Rs(1008+14) =1022
