A - 7900

B - 8100

C - 8300

D - 8500

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.

A - 45

B - 50

C - 55

D - 60

Answer : D

Explanation

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

Q 3 - If 0.6*A= 0.09*B, then A:B= ?

A - 2:3

B - 1:15

C - 20:3

D - 3:20

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

Q 4 - If 2A =3B and 4B=5C,then A:C=?

A - 3:4

B - 15:8

C - 8:15

D - 4:3

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 ?

A - 1

B - 3

C - 6

D - 8

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 :

A - 25

B - 64

C - 48

D - 129

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

A - 5:3

B - 7:1

C - 3:4

D - 9:7

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:

A - 1250

B - 1000

C - 850

D - 750

Answer : A

Explanation

Ratio of the amounts collected form 1stand 2nd  class fares
    =(3*1:1*50)=3:50.
Amount collected from 2nd   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?

A - 280

B - 150

C - 170

D - 200

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:

A - 864
