Q 1 - The ratio of money with Raju and Babu is 9:19 and that with Babu and Shyam is 9:19.if Raju has Rs.567,Babu has

### Answer : A

**Explanation**

Raju:Babu = 9:19 = 81:171 Babu:Shyam = 9:19 = 171:361 => Raju:Shaym = 81:361 => 81:361 = 567:x =>x = 2527

Q 2 - Rs. 960 was divided among three sons Qavi, Shafi and Rafi. If each of them had received Rs 45 less, their shares would have been in the ratio of 3:5:7. What was the amount received by Qavi?

### Answer : D

**Explanation**

Total =Rs.960 If each of them receives Rs.45 less then 960-(45*3) =825 Ratio being 3:5:7 =>3x+5x+7x=825 =>x=55 Qavi's amount = (3x) +45=(3*55)+45=Rs.210

Q 3 - If A:B =1/2:3/8 , B:C =1/3:5/9 and C:D =5/6:3/4 then , A:B:C:D=?

### Answer : C

**Explanation**

A:B = 1/2 : 3/8 =4 :3 , B:C = 1/3 :5/9 = 3:5 and C:D = 5/6 : 3/4 = 10 :9 A:B = 4:3 , B:C = 3 :5 , C:D = 10/2 :9/2 = 5 :9/2 A:B:C:D = 4:3:5:9/2 = 8 :6: 10 :9

### Answer : D

**Explanation**

Let x/5=y/8 = k ,then x = 5k and y = 8k &therw4; x+5/y+8 = 5k+5 / 8k +8 = 5(k+1)/ 8(k+1) = 5/8 => (x+5) : (y+8 ) = 5:8

Q 5 - The proportion of young men and young ladies in a school is 3:2 . at the point when 6 more young ladies join , this proportion gets to be 6:5 . What are number of young men there in the school?

### Answer : D

**Explanation**

Let the quantity of young men and young ladies be 3x and 2x individually. At that point ,3x/(2x+6)=6/5 ?15x=12x+36?3x=36?x=12. Number of boys=(3*12)=36.

Q 6 - The proportion of winning of An and B is 8:9 , if the gaining of An is expanded by half and procuring of B is diminished by 25%, the new proportion of their acquiring is 16:9 , what are An acquiring?

### Answer : D

**Explanation**

New earnings of A and B=Rs (150% of 8x), Rs (75%of 9x) =Rs (150/100*8x), Rs (75/100*9x) = Rs 12x,Rs 27x/4 Ratio of new earnings = 12x: 27x/4 = 48:27 = 16:9. Thus, we cannot find A's earnings.

Q 7 - Two numbers are separately 20% and half all the more than a third Number. These two numbers are in the proportion:

### Answer : B

**Explanation**

Let the 3^{rd}number be X. Then, 1^{st}number = 120% of X= (120/100*X)= 6x/5 2^{nd}number= 150 % of X= (150/100 *X) =3x/2 ∴ Ration of these no. = 6x/5 :3x/2 =12:15 =4:5

Q 8 - Rs. 680 is separated among A, B, C such that A gets 2/3 of what B gets and B gets 1/4 of what C gets. At that point their shares are separately:-

### Answer : B

**Explanation**

Suppose C gets Rs. x. then B gets Rs. x/4 and gets Rs. (2/3*x/4)= x/6. ∴x/6+x/4+x=680 =>2x+3x+12x=8160 => 17x= 8160 => x=480 ∴ A gets rs. 80, B gets rs. 120 and C gets rs. 480

Q 9 - An entirety of cash is isolated among A, B and C in a manner that to every rs. A gets 100, B gets 65 paisa and C gets 35 paisa. If C offer is 28, the total is:

### Answer : C

**Explanation**

A:B:C=100:65:35 = 20:13:7 If C share is 7, sum is (20+13+7). If C share is 28, sum is (40/7*28)= 160

Q 10 - Vessels An and B contain blends of milk and water in the proportion 4:5 and 5:1 separately .in what proportion ought to amounts of blends be taken From A to B to shape a blend in which drain to water is in the proportion 5:4?

### Answer : D

**Explanation**

Let the required ratio be X:1 Milk in x ltr. of 1st mix= (x*4/9)= 4x/9 ltr. Water in x ltr. of 1st mix= (x-4x/9)= 5x/9 ltr. Milk in 1 ltr. of 2nd. Mix= 5/6 ltr. Water in 1 ltr. of 2nd. Mix= {1-5/6}=1/6 ltr. Milk: water =(4x/9+5/6): (5x/9+1/6) =(8x+15)/18: (10x+3)/18 ∴ (8x+15)/(10x+3) =5/4 => 4(8x+15)= 5(10x+3) = 18x=45 =>x=5/2 Required ratio : 5/2:1 =5:2
