Q 1 - X's money is to Y's money as 5:7 and Y's money is to Z's money as 3:4 .If X has Rs.900, Z has
Answer : D
Explanation
X:Y = 5:7 = 15:21, Y:Z = 3:4 = 21:28 X:Y:Z = 15:21:28 X:Z = 15:28 800:Z = 15:28 =>Z = Rs.1680.
Q 2 - Two numbers are respectively 80% and 60% more than a third number. What is the ratio between two numbers?
Answer : C
Explanation
Let the third number be x => The first and second number becomes 1.8x and 1.6x Their ratio will be 1.8x/1.6x=1.8/1.6=9/8 = 9:8
Answer : D
Explanation
0.6*A = 0.09 *B A/B =0.09/0.6 = 0.09/0.60 = 9/60 =3/20 ∴A:B = 3:20
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 - The proportion between two no. is 3:4 . on the off chance that every no. is expanded by 6, the proportion gets to be 4:5 . The no's distinction. is ?
Answer : C
Explanation
Let the numbers be 3x and 4x. At that point, 3x+6/4x+6 = 4/5 => 5 (3x+6) =4 (4x+6) => x=(30-24) =6 Contrast between the numbers = (4x-3x) = x = 6.
Q 6 - Two no. are in the extent of 3:5 . If each no. is extended by 10, the extent gets the opportunity to be 5:7 , the no. are?
Answer : D
Explanation
Let the numbers be 3x and 5x then, (3x+10 ) / (5x+10)= 5/7 => 7 ( 3x+10)= 5 (5x+10) => 4x= (70-50) =20 => x =5 ∴ The numbers are (3*5) and (5*5) , 15 and 25
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 a surpasses B by 40 % and B is not as much as C by 20 %, then A:C =?
Answer : D
Explanation
B= 80% of C= 80/100*C= 4c/5 and A= 140% of B=(140b/100) =7B/5 A= 7b/5= 7/5*4C/5 =28C/25 =>A/C =28/25 ∴ A: C = 28:25
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 - 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.
