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 :

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 - If 18: x=x: 18, then x is equal to:

A - 18

B - 324

C - 9

D - 4.24

### Answer : A

Explanation

```18: x=x: 18
=>18/x=x/18=>x=18
```

Q 3 - If A:B =1/2:3/8 , B:C =1/3:5/9 and C:D =5/6:3/4 then , A:B:C:D=?

A - 3:2:4:5

B - 6:8:9:10

C - 8:6:10:9

D - 2:3:4:5

### Answer : C

Explanation

```A:B = 1/2 : 3/8 =4 :3 ,
B:C = 1/3 :5/9 = 3:5
and C:D = 5/6 : 3/4 = 10 :9
A:B = 4:3 , B:C = 3 :5
, C:D = 10/2 :9/2 = 5 :9/2
A:B:C:D = 4:3:5:9/2 = 8 :6: 10 :9
```

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 - If 20 % of (p +q )=50 % of (p-q ), then p:q =?

A - 5:7

B - 7:5

C - 7:3

D - 7:8

### Answer : C

Explanation

```20/100* (P+Q) = 50/100* (P-Q)
=> 20 * (P+Q)=50 *(P-Q)
=> 20P +20Q = 50P-50Q
=> 30P=70Q
=> P/Q=70/30=7/3
=> P:Q = 7:3.
```

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 - At the point when 20% of a no. is added to another no., the no. increment by half. What is the proportion between the first and the second no?

A - 3:2

B - 2:3

C - 5:2

D - cannot be resolved

### Answer : C

Explanation

```Let the numbers be x and y. Then,
Y+ 20x/100 = (150/100)y
=> x/5 ={ (3/2)y-y}= y/2
=> 2x-5y
=> x/y=5/2
=> x:y =5:2
```

Q 8 - Rs. 355 were separated among A, B,C in a manner that A had Rs. 20 more than B and C had Rs.15 all the more than A . What amount was C offer?

A - 100

B - 120

C - 135

D - 150

### Answer : C

Explanation

```Suppose B gets Rs. X. Then, A gets Rs. (x+20) and C gets Rs. (x+35)
∴ x+20+x+x+35= 355 => 3x=300
=>x=100
∴ C share= (100+35) =135.
```

Q 9 - Rs. 5625 are separated among A, B and C so that A receives 1/2 as much as B and C together gets and B gets 1/4 of what An and C together gets. The offer of A is more than B by:

A - 750

B - 775

C - 1500

D - 1600

### Answer : A

Explanation

```A= 1/2(B+C)
=> B+C= 2A
=> A+B+C= 3A
∴ 3A = 5625
=> A= 1875.
B= 1/4 (A+C)
=> A+C =4B
=> A+B+C = 5B
∴ 5B = 5625
=> B =1125
Hence, (A-B) = (1875-1125) =750
```

Q 10 - Vessels An and B contain blends of milk and water in the proportion 4:5 and 5:1 separately .in what proportion ought to amounts of blends be taken From A to B to shape a blend in which drain to water is in the proportion 5:4?

A - 2:5

B - 2:3

C - 4:3

D - 5:2

### Answer : D

Explanation

```Let the required ratio be X:1
Milk in x ltr. of 1st mix=  (x*4/9)= 4x/9 ltr.
Water in x ltr. of 1st mix= (x-4x/9)= 5x/9 ltr.
Milk in 1 ltr. of 2nd. Mix= 5/6 ltr.
Water in 1 ltr. of 2nd. Mix= {1-5/6}=1/6 ltr.
Milk: water =(4x/9+5/6): (5x/9+1/6) =(8x+15)/18: (10x+3)/18
∴ (8x+15)/(10x+3) =5/4
=> 4(8x+15)= 5(10x+3)
= 18x=45
=>x=5/2
Required ratio : 5/2:1 =5:2
