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 - 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
Q 3 - If A:B =1:3 , B:C =5:7 , C:D =9:7 ,then A:B:C:D =?
Answer : C
Explanation
A:B = 1 :3 = 5 :15 , B :C = 5:7 =15 :21 and C:D = 21/9 *9 : 21/9 *7 A: B = 5:15 , B :C = 5:7 and C:D =21:49/3 A : B :C :D = 5 :15 :21 : 49/3 => A : B :C :D = 15 :45 : 63 : 49
Answer : C
Explanation
1/x *1/x =1/5 *1/1.25 => 1/x2=1/6.25 => x2 =6.25 => x =&sqrt;6.25 = 2.5
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 - Instead of partitioning rs. 117 among P, Q, R in the proportion 1/2: 1/3:1/4, by misstep it was isolated in the proportion 2:3:4 . who picked up in the exchange?
Answer : D
Explanation
P = Rs(117*6/13)= Rs 54, Q = Rs(117*4/13)= Rs 36 And R = Rs(117*3/13)=Rs 27. Again, the ratio is 2:3:4. P =Rs(117*2/9)= Rs 26, Q= Rs (117*3/9)=Rs 39 And R=RS(117*4/9)=Rs 52. Thus, both Q and R gained in the transaction.
Q 7 - Two entire numbers whose entirety is 64, cannot be in the proportion
Answer : C
Explanation
For dividing 64 in to two whole numbers, the sum of the terms of the ratio must be a factor of 64. So, they cannot be in the ratio 3:4
Q 8 - Three no. are in the proportion 3:4:5. The total of the biggest and the littlest measures up to the third's entirety and 52. The littlest no. is?
Answer : C
Explanation
Let the numbers be 3x, 4x and 5x. (5x+3x) = 4x+52 => 4x =52 => x=13 Smallest no. = (3*13) = 39
Q 9 - Rs. 1050 is partitioned among p, q and r in a manner that the offer of p is 2/5 of the consolidated offer of q and r. Therefore p gets:
Answer : B
Explanation
Given: P=2/5 (Q+R) => P :( Q+R)= 2:5 ∴ P share =(1050*2/7)= 300.
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.
