Q 1 - The ratio between Hyder's and Siddiq's age at present is 3:5.Hyder is 8 years younger then Siddiq. The ratio of Hyder's age to Siddiq's age after 8 years will be:

### Answer : C

**Explanation**

Let their ages be 3x and 5x years. 5x-3x=8 or x=4. Hyder's age = 3x =12 and Siddiq's age = 5x =20. After 8 years Hyder's age = 12+8 = 20 After 8 years Siddiq's age = 20+8 =28 Ratio of their ages 20:28 = 5:7

Q 2 - The difference between two positive numbers is 20 and their ratio is 3:2.Find the product of the two numbers?

### Answer : B

**Explanation**

Let the numbers be X and Y Difference between the numbers is 20 =>X-Y=20 ------- (1) Ratio of the numbers is 3:2 =>X/Y=3/2 -------- (2) From eqn 1 & 2 3/2 Y-Y=20=>Y=20 & X=40 X*Y=800

### 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 : D

**Explanation**

Let x/5=y/8 = k ,then x = 5k and y = 8k &therw4; x+5/y+8 = 5k+5 / 8k +8 = 5(k+1)/ 8(k+1) = 5/8 => (x+5) : (y+8 ) = 5:8

Q 5 - On separating a total of rs. 832 in the middle of An and B in the proportion 1/3 :1/5 , there offer are :

### Answer : A

**Explanation**

Given ratio =1/3: 1/5 = 5:3 I^{st}part=Rs(832*5/8)=Rs 520; 2^{nd}part = Rs(832*3/8)=Rs 312.

Q 6 - The month to month pay of An and B are in the proportion 2:3 and their month to month costs are in the proportion 6:9. On the off chance that each of them recovery 600 rs for every month, then their month to month wage?

### Answer : C

**Explanation**

Let the incomes of A and B be Rs 2x and Rs 3x respectively and their Expenditures are Rs 5y and Rs 9y respectively. Then, 2x-5y=600 ... (i) and 3x-9y=600 => x- 3y=200 ... (ii) On solving (i) and (ii) , we get x =800. So, their incomes are Rs.1600 and Rs.2400 respectively.

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?

### 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. 680 is separated among A, B, C such that A gets 2/3 of what B gets and B gets 1/4 of what C gets. At that point their shares are separately:-

### Answer : B

**Explanation**

Suppose C gets Rs. x. then B gets Rs. x/4 and gets Rs. (2/3*x/4)= x/6. ∴x/6+x/4+x=680 =>2x+3x+12x=8160 => 17x= 8160 => x=480 ∴ A gets rs. 80, B gets rs. 120 and C gets rs. 480

Q 9 - An entirety of cash is isolated among A, B and C in a manner that to every rs. A gets 100, B gets 65 paisa and C gets 35 paisa. If C offer is 28, the total is:

### Answer : C

**Explanation**

A:B:C=100:65:35 = 20:13:7 If C share is 7, sum is (20+13+7). If C share is 28, sum is (40/7*28)= 160

Q 10 - Two equivalent glasses are 1/3 and 1/4 loaded with milk. They are then topped off with the water and the substances are blended in a tumbler. The milk's proportion and water in the tumbler is:

### Answer : B

**Explanation**

First glass contains milk =1/3, water=2/3. Second contains milk =1/4,water=3/4. New tumbler contains milk=(1/3+1/4)=7/12,water=(2/3+3/4)=17/12. Ratio of milk and water in it =7/12:7/12=7:17.
