C
33.14

D
29.87

Solution

Solution: Given,
Capacity of the barrel = 46.32 liters
Amount of water used= 11.19 liters
Amount of water left in the barrel = 46.32 – 11.19 = 35.13 liters
Question 2
1 / -0

Add- 3.8 and 8.7

A
9.5

B
10.5

C
11.5

D
12.5

Solution

3.8 and 8.7
So we get
3.8 + 8.7=12.5
Question 3
1 / -0

What will be the diameter of a circlehaving circumference of 16.09 cm. Take π=3.14?

A
6

B
6.25

C
5.12

D
4

Solution

Given, circumference = 16.09 cm
Circumference of a circle, C=2πr
⇒16.09=2πr
⇒16.09=2×3.14×r
⇒r=16.09×1006.28×100
⇒r=2.56 cm
Therefore Diameter = 2r = 2 x 2.56 = 5.12 cm.
Question 4
1 / -0

Add 12.95 and 2.003, and from the result, subtract the sum of 3.794 and 5.2.

A
6.586

B
2.245

C
5.959

D
5.482

Solution

We know that addition of 13.95 and 1.003 can be written as
13.95 + 1.003 = 14.953
Similarly the sum of 2.794 and 6.2 can be written as
2.794 + 6.2 = 8.994
Here the difference between 14.953 and 8.994
14.953 – 8.994 = 5.959
Question 5
1 / -0

A
2.2531

B
1.2521

C
3.2521

D
4.2521

Solution

0.4136, 0.3195 and 0.52
So we get
0.4136 + 0.3195 + 0.52 = 1.2531
Question 6

Convert 3.75 into lowest terms:

A
12/4

B
13/4

C
14/4

D
15/4

Solution

3.75
We can write it as
= 375/ 100
Here the HCF of 375 and 100 is 25
= (375 ÷ 25)/ (100 ÷ 25)
So we get
= 15/4
