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=?

### 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

### 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 - The proportion of young men and young ladies in a school is 3:2 . at the point when 6 more young ladies join , this proportion gets to be 6:5 . What are number of young men there in the school?

Q 8 - The whole of three square of three no. which are in the proportion 2:3:4 is 725. What are three numbers?

### Answer : A

**Explanation**

Let the numbers be 2x, 3x and 4x. Then, 4x^{2}+9x^{2}+16x^{2}= 725 => 29x^{2}=725 x^{2}= 25 => x =5 ∴ The numbers are 10, 15, 20 .

Q 9 - Rs. 53 is isolated among A, B and C in a manner that A gets rs.7 more than what B gets and B gets rs. 8 more than what C gets. The proportion of their offer is:

### Answer : B

**Explanation**

Let C=x Then, B= (x+8) and A =(x+15) ∴ x+15+x+8+x =53 =>3x =30 => x=10 ∴ A:B:C=25:18:10.

Q 10 - Three equivalent glasses are loaded with blend of soul and water. The proportion of sprit and water is given underneath:- first glass = 3:4 , second glass =4:5 ,third glass =5:6 The substance of three glasses are purged into a solitary vessel.
