Q 1 - Divide Rs. 1500 among U,V,W,X so that u and V together get thrice as much as W and X together, V gets four times of what W gets and W gets 1.5 times as much as X. V gets Rs

### Answer : B

**Explanation**

U+V+W+X=1500 ------ (1) Here U+V=3(W+X) From (1) And 4(W+X) =1500 => W+X=375 U+V=1125 Given that V=4W & W=1.5X => 2.5X = 375 => X=150 => V=4*1.5*X=900

Q 2 - The speed of three trains is in the ratio 3:5:7. The ratio between the time taken by these trains to travel the same distance is

### Answer : A

**Explanation**

Speeds are in the ratio 3:5:7 Ratio of time taken will be 1/3:1/5:1/7 => 35/105:21/105:15/105 =35:21:15

### 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**

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 - Rs. 6400 are separated among three laborers in the proportion 3/5 :2 : 5/3 . The offer of second specialist is ?

### Answer : B

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 - Rs. 53 is isolated among A, B and C in a manner that A gets rs.7 more than what B gets and B gets rs. 8 more than what C gets. The proportion of their offer is:

### Answer : B

**Explanation**

Let C=x Then, B= (x+8) and A =(x+15) ∴ x+15+x+8+x =53 =>3x =30 => x=10 ∴ A:B:C=25:18:10.
