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

### Answer : A

**Explanation**

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

### Answer : A

**Explanation**

A/C = (a/b *b/c) = (2/3*4/5 ) = 8/15 C/A =15/8 , so C:A = 15:8

### Answer : B

**Explanation**

0.4*X =1.4 *1.4 => X=1.4*1.4/0.4 =14*14/10*4 =49/10= 4.9

Q 5 - In a school, the proportion of young men and young ladies is 4:5 . at the point when 100 young lady leaves the school , the proportion gets to be 6:7 . What are number of young men are there in the school?

### Answer : B

**Explanation**

Let the number of boys and girls be 4x and 5x respectively. Then,4x/5x-100=6/7?28x=30x-600 =>2x=600 => x=300. Number of boys=(4*300)=1200.

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 - Three numbers A , B and C are in the proportion 1:2 :3. Their normal is 600. In the event that An is expanded by 10% and B is diminished by 20 %, then to get the normal expanded by 5%, C will be expanded by:

### Answer : D

**Explanation**

Let A= x, B= 2x and C=3x, then, (X+2x+3x)/3 =600 => 6x =1800 =>x= 300 ∴ the numbers are 300, 600, 900. New average= 105% of 600 =(105/100*600)= 630. Let 110% of 300+ 80% of 600 +y=630*3 => (110/100*300) +(80/100*600)+y =1890 => (330+480)+y= 1890 => y=1890-810 =1080 Increase in C= (1080-900) =180.

Q 9 - Some cash is isolated among A, B and C in a manner that 5 times An offer ,3 times of B's offer and 2 times C offer are all equivalent . The proportion between the offer of A, B, c is:

### Answer : D

**Explanation**

Let 5A= 3B= 2C=k. Then, A = k/5, B = k/3 and C = k/2 ∴ A:B:C =k/5 :k/3:k/2 =6:10:15.

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
