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
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
Answer : B
Explanation
15/100 a = 20/100 b => 15 A = 20 B =>A/B = 20/15 = 4/3 Thus A:B =4 :3
Answer : B
Explanation
2A =3B thus A/B=3/2 and 4B=5C thus B/C = 5/4 ∴ A/C=(A/B*B/C) = (3/2*5/4) = 15/8 A:C =15:8.
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 - In a class, the no. of young women is 20% more than that of the young fellows. The class' quality is 66. If 4 more young women are admitted to the class, what will be the no's extent of young fellows to that of the young women?
Answer : C
Explanation
Let the number of boys be x. Then the no. of girls = 120% of x = (120/100 *X)= 6X/5 . X+6x/5 =66 => 5x+6x=330 => 11x= 330 => x= 3 Now, the no. of boys= 30 , no. of girls =[6/5*30 +4]=40 Now the ratio of boys and girls = 30/40 = 3/4 =3:4
Q 7 - What ought to be added to each of the four numbers 6, 14, 18, 38 to make them corresponding?
Answer : B
Explanation
Let the number to be added be x. Then, 6+X/14+x= 18+x/38+x => (6+x) (38+x)= (14+ x) (18 +x) => 228 +44x+x<sup>2</sup> = 252+32x+x<sup>2</sup> = 12x=24 => x=2 . ∴ the required number is 2.
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 - Some cash is isolated among A, B and C in a manner that 5 times An offer ,3 times of B's offer and 2 times C offer are all equivalent . The proportion between the offer of A, B, c is:
Answer : D
Explanation
Let 5A= 3B= 2C=k. Then, A = k/5, B = k/3 and C = k/2 ∴ A:B:C =k/5 :k/3:k/2 =6:10:15.
Q 10 - A and B are two compounds of gold and copper arranged by blending metals in the extent 7:2 and 7:11 separately. In the event that the equivalent amounts of the combination are dissolved to frame a third amalgam C, the extent of gold and copper In C will be:
Answer : C
Explanation
Gold in C=(7/9+7/18)=21/18=7/6. Copper in C=(2/9+11/18)=15/18=5/6. ∴Gold:Copper=7/6:5/6=7:5.
