Q 1 - If three numbers are in the ratio 3:7:11 and double the sum is 84, then the ratio of squares of the numbers is
Answer : B
Explanation
Let the numbers are 3x:7x:11x It is given that 2(3x+7x+11x) = 84 => x=2 Ratio 6:14:22 or 3:7:11 Their squares 9:49:121
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 : A
Explanation
A/C = (a/b *b/c) = (2/3*4/5 ) = 8/15 C/A =15/8 , so C:A = 15:8
Answer : D
Explanation
X * 17.5 =7*22.5 => X= 7*22.5/17.5 = 7*225/175 =9.
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
Explanation
Given ratio=3/5:2/1:5/3=9:30:25. Share of the second workers = Rs(6400*30/64)=Rs 3000.
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 - 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 - 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 - In a blend of 60 liters, the proportion of milk and water is 2:1. In the event that this proportion. Is to be 1:2, the amount of water to be further included is:
Answer : D
Explanation
Quantity of milk=(60*2/3) liters =40 liters ,Water in it 20 liters. Let the required quantity of water to be added be x liters. Then , 40/20+x=1/2 =>20+x=80 =>x=60. ∴Water to be added=60 liters.
