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 - If 420 Mangoes was distributed among three children's in the ratio 1/3:2/3:3/4 , how many bananas did the first child get?

Answer : B

Explanation

1/3:2/3:3/4=(4:8:9)/12
Mangoes are in the ratio 4x:8x:9x
 4x+8x+9x = 420
=> x=20
 => First child get 4*20=80 mangoes

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

Q 4 - If x:y =3:4 ,then (7x+ 3y): (7x-3y)=?

Answer : C

Explanation

Now x/y =3/4
(7x+3y)/(7x-3y)  = (7 * x/y + 3)/(7 * x/y -3)
= (7 *3/4 +3)/(7* 3/4  - 3 ) 
= (21+12)/(21-12) = 33/9 =11/3
∴  (7x+3y) : (7x-3y)= 11:3

Q 5 - Which of the following function can be used to get an array in the reverse order?

Answer : A

Explanation

array_reverse(): Returns an array in the reverse order.

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 - The proportion of two numbers is 3:4 and their entirety is 420.The more noteworthy of the Two numbers is:

Answer : C

Explanation

Let the numbers be 3x and 4x , Then
3x+4x= 420
=> 7x= 420 
=>  x=60.
 So, the numbers are 180 and 240.
 Hence, the correct answer is 240 .

Q 8 - if the wage of A is 10% more than that of B and the wage of B is 20 % not as much as that of C, than the pay of A,B, C are in the proportion.

Answer : B

Explanation

Let C income be Rs 100. Then, B income=Rs 80.
A income=(110% of Rs 80)=Rs(110/100*80)=Rs 88.
∴A:B:C=88:80:100=22:20:25.

Q 9 - Rs. 600 are partitioned among A, B and C such that Rs. 40 more than 2/fifth of An offer , Rs. 20 more than 2/7 of B offer and Rs. 10 all the more then 9/17 of C offer may all be equivalent . What is A's offer?

Answer : B

Explanation

(2/5)A +40 = ( 2/7)B +20 + 9/17 C+10 = k.
Then, A =5/2 (k-40), B= 7/2(k-20) and C= 17/9 (k-10)
A+B+C =600 =>5/2 (k-40) +7/2(k-20) + 17/9 (k-10) = 600
=> 45(k-40) +63(k-20)+34(k-10)= 10800
=> 142k- (45*40+63*20+34*10) =10800
=> 142k- (10800+3400) = 14200 
=>k=100.
∴ A= 5/2(100-40)= (5/2*60) =150

Q 10 - Rs 1300 are separated among A,B,C and D in a manner that: A share / B share = B share / C share =C share/ D share = 2/3, What is A share?

Answer : C

Explanation

A:B=2:3,B:C=2:3=3/2*2:3/2*3:9/2.
C:D=2:3=2*9/4:3*9/4=9/2:27/4.
∴ A:B:C:D=2:3:9/2:27/4=8:12:18:27.
A share =Rs(1300*8/65)=Rs160.
