Q 1 - A certain amount was divided between Sangeetha and Sunita in the 5:4. If Sunita's share was Rs.3600,the amount is :

### Answer : B

**Explanation**

Let their shares be Rs. 5x and 4x. Thus, 4x=3600 =>x=900 Total amount =9x=Rs.8100.

Q 2 - Three numbers in the ratio 2:3:5 add up to give a sum of 120.Find the value of biggest number.

### Answer : D

**Explanation**

Let the numbers are 2x:3x:5x 2x+3x+5x=120 => x=12 5x=5*12=60

### 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**

2A =3B thus A/B=3/2 and 4B=5C thus B/C = 5/4 ∴ A/C=(A/B*B/C) = (3/2*5/4) = 15/8 A:C =15:8.

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 - In an extent which is proportionate to 5:8 , if the harbinger is 40, then the subsequent is :

### Answer : B

**Explanation**

Let the consequent be X. Then, 5/8 =40/x => 5x=8*40 => x=64 ∴ Consequent is 64.

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 - The proportion of first and worthless train passages between two stations is 3:1 and that of the no. of traveler going between two these by first and inferior 1:50 . in the event that on a specific day rs.1325 be gathered from the travelers going between these stations, then the sum gathered from useless travelers is:

### Answer : A

**Explanation**

Ratio of the amounts collected form 1^{st}and 2^{nd}class fares =(3*1:1*50)=3:50. Amount collected from 2^{nd}class passengers=Rs (1325*50/53) = Rs 1250.

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 - Rs 3068 are circulated among A,B and C such that on diminishing Their shares by Rs 10,Rs 14 and Rs 20 individually, the parity cash would be isolated among then in the proportion 5:6:7. at that point ,B offer is:

### Answer : B

**Explanation**

Money in the ration 5:6:7 is Rs (3068 -44) =Rs 3024. ∴B share =Rs{(3024*6/18)+14}=Rs(1008+14) =1022
