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
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 : B
Explanation
Let 1/x = 2k , 1/y = 3k and 1/z = 5k At that point x = 1/2k, y =1/3k, z = 1/5k ∴ x:y:z = 1/2k : 1/3k: 1/5k ∴ x:y:z = 15:10:6
Q 5 - On the off chance that a:b =c:d =e: f =1:2 , then (3a+5c+7e) : (3b +5d +7f ) = ?
Answer : A
Explanation
a/b=c/d=e/f=1/2?a= b/2,c=d/2 and e=f/2. ∴ (3a+5c+7e)/(3b+5d+7f) = (3b/2+5d/2+7f/2)/(3b+5d+7f) = 1/2(3b+5d+7f)/3b+5d+7f) = 1/2. => (3a+5c+7e):(3b+5d+7f)= 1:2.
Q 6 - If 32 understudies In a class are females and the proportion of females to guys understudy is 16:9 , then what % of the class is females ?
Answer : D
Explanation
Let the females be16x and males 9x .
Then, 16 x = 32
=> x=2
So, there are 32 females and 18 males in the class.
Percentage of females = {32/50*100)% = 64 %
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 - Which of the accompanying is the most reduced proportion?
Answer : C
Explanation
7/13 =0.538, 17/25 =0.68, 7/15= 0.466, 15/23 =0.652 Clearly, 7/15 is the smallest.
Q 9 - Rs. 5625 are separated among A, B and C so that A receives 1/2 as much as B and C together gets and B gets 1/4 of what An and C together gets. The offer of A is more than B by:
Answer : A
Explanation
A= 1/2(B+C) => B+C= 2A => A+B+C= 3A ∴ 3A = 5625 => A= 1875. B= 1/4 (A+C) => A+C =4B => A+B+C = 5B ∴ 5B = 5625 => B =1125 Hence, (A-B) = (1875-1125) =750
Q 10 - Two equivalent glasses are 1/3 and 1/4 loaded with milk. They are then topped off with the water and the substances are blended in a tumbler. The milk's proportion and water in the tumbler is:
Answer : B
Explanation
First glass contains milk =1/3, water=2/3. Second contains milk =1/4,water=3/4. New tumbler contains milk=(1/3+1/4)=7/12,water=(2/3+3/4)=17/12. Ratio of milk and water in it =7/12:7/12=7:17.
