**(a) 4 : 9**

**(b) 40 : 9**

**(c) 9 : 40**

**(d) 20 : 9**

**Answer- 1**

4l : 900 mL,

= 4000 mL : 900 mL,

= 4000 : 900,

= 40 : 9

**Question -2 ****When the number 210 is increased in the ratio 5 : 7, the the new number is**

**(a) 150**

**(b) 180**

**(c) 294**

**(d) 420**

**Answer -2 **

210 is increased in the ratio 5 : 7, then

New increased number will be = 210 × 7/5

= 294

**Question-3 ****Two numbers are in the ratio 7 : 9. If the sum of the numbers is 288, then the smaller number is**

**(a) 126**

**(b) 162**

**(c) 112**

**(d) 144**

**Answer -3**

Ratio in two number = 7 : 9

Sum of numbers = 288

Sum of ratios = 7 + 9 = 16

Smaller number = (288 × 7)/16

= 126

**Question -4 ****The ratio of number of edges of a cube to the number of its faces is**

**(a) 2 : 1**

**(b) 1 : 2**

**(c) 3 : 8**

**(d) 8 : 3**

**Answer -4 **

No. of edges of the cube = 12

No. of faces = 6

Ratio in edges a cube to the number of faces = 12 : 6

= 2 : 1

**Question-5 ****If x, 12, 8 and 32 are in proportion, then the value of x is**

**(a) 6**

**(b) 4**

**(c) 3**

**(d) 2**

**Answer-5 **

x, 12, 8, 32 are in proportion, then

x × 32 = 12 × 8 **(∵ ad = bc)**

⇒ x = (12 × 8)/32 = 3

x = 3

**Question-6 ****The fourth proportional to 3, 4, 5 is**

**(a) 6**

**(b) 20/3**

**(c) 15/4**

**(d) 12/3**

**Answer-6**

The fourth proportion to 3, 4, 5 will be

= (4 × 5)/3

= 20/3

**Question-7 ****The third proportional to 25/4 and 5 is**

**(a) 4**

**(b) 17/2**

**(c) 3**

**(d) none of these**

**Answer-7**

The third proportional to 6.1/4 and 5 is

⇒ 6. 1/4 : 5 : : 5 : x

⇒ 25/4 : 5 : : 5 : x

⇒ x = {(5 × 5)/25} × 4,

⇒ 4

**Question-8 ****The mean proportional between 1/2 and 128 is**

**(a) 64**

**(b) 32**

**(c) 16**

**(d) 8**

**Answer-8**

The mean proportional between 1/2 and 128 is

= √(1/2)x128 = √64 = 8 (d)
