Hello Aspirants. Welcome to Online Quantitative Aptitude section in AffairsCloud.com. Here we are creating question sample in Ratio & Proportion , which is common for all the competitive exams. We have included Some questions that are repeatedly asked in exams !!

**The salaries of A,B and C are in the ratio 5:3:2.If the increments of 20% ,10% and 20% are allowed in their salaries, then what will be the new ratio of their salaries ?**

A)22:11:9

B)22:10:8

C)20:11:8

D)20:10:9

E)None of these**Answer – C) 20:11:8**

Explanation :

5:3:2 = 500:300:200

500Ã—(20/100) = 100 => 500+100 = 600

300Ã—(10/100) = 30 => 300+33 = 330

200Ã—(20/100) = 40 => 200+40 = 240

600:330:240 = 20:11:8**Two numbers are respectively 40% and Â 60% more than than the third number. The ratio of the two number is**

A)6:7

B)7:8

C)8:7

D)7:5

E)None of these**Answer – B) 7:8**

Explanation :

Let third number = x

(140/100)x = (7/5)x

(160/100)x = (8/5)x

(7/5) : (8/5) = 35 : 40 = 7 : 8**A sum of money is to be distributed among P , Q , R and S in the proportion 2:5:6:7, If R get Rs.500 more than S,what is Pâ€™s share ?**

A)500

B)700

C)1000

D)1200

E)None of these**Answer – C) 1000**

Explanation :

S â€“ R = 7 â€“ 6 = 1 => 500

2 Ã— 500 = 1000**Ratio of earnings of A and B is Â 3:5. If the earnings of A increase by 25% and those of B decrease by 30%, the new ratio of their earnings become 6:8.What is Aâ€™s earnings ?**

A)16,000

B)34,000

C)15,000

D)32,000

E)Data inadequate**Answer – E)Â Data inadequate**

Explanation :We cant derive the earnings from the given details**The sum of the three number is 68.If the ratio of the first to second is 3:2 and that of the second to the third is 5:3 , then the second number is**

A)21

B)22

C)23

D)24

E)None of these**Answer -B) 22**

Explanation :

A: B = 3:2

B:C = 5 : 3

B:C =(5Ã—[2/5]) : (3Ã—[2/5])= 2: (6/5)

A:B:C = 3:2:(6/5) = 15:10:6

Second number = (10/31)Ã—68 = 21.9 = 22**The ratio of prices of 2 dresses is 10:15.If the price of the first dress is increased by 10% and that of the second dress by Rs.400 then the ratio of their prices is 4:7.What are the initial prices of the dresses ?**

A)91

B)92

C)93

D)94

E)None of these**Answer -D) 94**

Explanation :

Let the initial price of the dress = 10x and 15x

Price of the 1^{st}dress after increment = 10x Ã— (110/100) = 11x

Price of the^{2nd}dress after increment = 15x+400

[11x/(15x+400)] = 4/7

77x = 60x + 1600

17x = 1600

X = 1600/17 = 94.11 = 94**A Zoo has 66 fishes , some white and rest orange , Which of the following could be the ratio of white to orange fishes in the zoo ?**

A)1:7

B)2:9

C)3:7

D)2:5

E)None of these**Answer – B) 2:9**

Explanation :

2+9 = 11

66 can divisible by 11.**The ratio of the number of boys to that of girls in a school is 3:2. If 30% of boys and 70% of girls appeared in an examination, the ratio of students appeared in the examinations to that not appeared in the examination is**

A)23:27

B)22:25

C)21:17

D)18:17

E)None of these**Answer -A) 23: 27**

Explanation :

3:2 = 30:20

30% boys = (30/100) Ã— 30= 9

70% girls = (70/100) Ã— 20 = 14

(9+14) : (50-23) = 23 : 27**If 20% of x = 30% of y then x:y is**

A)2:3

B)3:2

C)1:2

D)1:3

E)None of these**Answer – B) 3:2**

Explanation :

(20/100)x = (30/100)y

x/y = (30Ã—100)/(100Ã—20) = 3/2 = 3:2**In a bag there are coins of 25p, 10p and 5p in the ratio 1:2:3.If there are Rs.45 in all then find how many 25p coins are there ?**

A)60

B)65

C)70

D)75

E)None of these**Answer – D) 75**

Explanation :

[(25x) + (10x Ã— 2) + (5x Ã— 3)] / 100 = 45

[25x + 20x + 15x] / 100 = 45

60 x = 4500

X = 4500/60 = 75
