(a) 12 1/2 (b) 84 (c) 19 (d) 112

**Question 2 :**

Solve the following equation :

p/9 = 3

(a) 3 (b) 6 (c) 9 (d) 27

**Question 3 :**

What is 6398 ÷ 14 ?

(a) 457 (b) 467 (c) 452 (d) 362

**Question 4 :**

What is the volume of the solid below, in cubic units.

(a) 6 cu.un (b) 10 cu.un (c) 14 cu.un (d) 12 cu.un

**Question 5 :**

Bose work as a dog walker. He charges fifteen dollars per dog and each day he walks eight dogs. How much would he earn in 7 days ?

(a) 630 (b) 720 (c) 750 (d) 840

**Question 6 :**

Select all the equivalent ratios to 6 : 15

(1) 3:5 (2) 2:5 (3) 12:30 (4) 18:45 (5) 1:1

(a) (1) & (2) (b) (2), (3) and (5)

(c) (2), (3) and (4) (d) (1), (3) and (5)

**Question 7 :**

Use the numbers shown to answer the question

{6, 9, 12, 15, ......}

Which describes this set of numbers ?

(a) odd numbers (b) Even numbers

(c) Prime numbers (d) Multiples of 3

**Question 8 :**

What fraction is between 1/5 and 1/2 ?

(a) 1/10 (b) 3/10 (c) 4/5 (d) 9/10

**(1) Solution :**

Using the given formula w = 7r

when r = 12

w = 7(12)

w = 84

**(2) Solution :**

p/9 = 3

Multiply by 9 on both sides, we get

p = 3(9)

p = 27

So, the value of p is 27.

**(3) Solution :**

6398 ÷ 14

= 6398/14

= 457

**(4) Solution :**

Total number of cubes in the figure given above is 12.

Volume of cubes = 12 cubic units.

**(5) Solution :**

Number of dogs he gives practice = 8

Charge per dog = $15

One day earning = 15(8)

= 120

His earning in 7 days = 120(7)

= 840

**(6) Solution :**

Given ratio is 6 : 15

Dividing the given ratio 6 : 15 by 3, we get 2 : 5

Multiplying it by 2, we get 12 : 30

Multiplying it by 3, we get 18 : 45

So, option C is correct.

**(7) Solution :**

{6, 9, 12, 15, ......}

By observing the given sequence, it is multiples of 3.

**(8) Solution :**

To find the fraction in between the given fractions, let us change the denominators of fraction as same.

(1/5) ⋅ (2/2) = 2/10

(1/2) ⋅ (5/5) = 5/10

So, the fraction lies in between the given fraction is 3/10.
