**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

Answer

Option (c) is correct

**Explanation –**

5:3:2 = 500:300:200

500×(20/100) = 100 , 500+100 = 600

300×(10/100) = 30 , 300+30 = 330

200×(20/100) = 40 , 200+40 = 240

600:330:240 = 20:11:8

**Two numbers are respectively 40% and 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

Answer

Option (b) is correct

**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 P’s share ?**

A)500

B)700

C)1000

D)1200

Answer

Option (c) is correct

**Explanation –**

S – R = 7 – 6 = 1

So, 1=500

Then, 2 × 500 = 1000

**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

Answer

Option (b) is correct

**Explanation –**

A: B = 3:2

B:C = 5 : 3

B:C =(5×[2/5]) : (3×[2/5])= 2: (6/5)

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

Second number = (10/31)×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

Answer

Option (d) is correct

**Explanation –**

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

Price of the 1^{st} dress after increment = 10x × (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
