Exercise 14(E)

1. From a rope of m long, m is cut off. Find the length of the remaining rope

Solution:

Given

Length of the rope = m

Length of cut off rope = m

Remaining rope =  We get

= 21 / 2 – 37 / 8

By taking LCM, we get

= (84 – 37) / 8

= 47 / 8 m

= Hence, the length of the remaining rope is m

2. A piece of cloth is 5 metre long. After washing, it shrinks by 1 / 25 of its length. What is the length of the cloth after washing?

Solution:

Given

Length of piece of cloth = 5 metre

After washing, it shrinks by = 1 / 25 of its length

Hence, the shrinked cloth can be calculated as below

Shrinked cloth = 1 / 25 of 5 m

= 1 / 5 m

Hence, length of cloth after washing can be calculated as below

Length of cloth after washing = 5 – 1 / 5

By taking LCM, we get

= (25 – 1) / 5

= 24 / 5

= m

Hence the length of cloth after washing is m

3. I bought wheat worth Rs , rice worth Rs and vegetables worth Rs . If I gave a hundred-rupee note to the shopkeeper; how much did he return to me

Solution:

Given

Wheat = Rs Rice = Rs Vegetables = Rs Hence, total amount used to purchase the goods can be calculated as below

Total amount of goods = Rs ( + + )

We get

= 25 / 2 + 103 / 4 + 41 / 4

= Rs 194 / 4

Hence, money returned by shopkeeper can be calculated as below

Money returned = Rs (100 – 194 / 4)

By taking LCM, we get

= Rs (400 – 194) / 4

= Rs 103 / 2

= Rs Hence, money returned by the shopkeeper is Rs 4. Out of 500 oranges in a box, 3 / 25 are rotten and 1 / 5 are kept for some guests. How many oranges are left in the box?

Solution:

Given

Number of oranges in a box = 500

Rotten oranges out of 500 = 3 / 25

Oranges for guests out of 500 = 1 / 5

Rotten oranges = 3 / 25 of 500

We get,

= 3 / 25 × 500

= 60

Oranges for guests = 1 / 5 of 500

We get,

= 1 / 5 × 500

= 100

Oranges left in box = 500 – 60 – 100

= 340

Hence, 340 oranges are left in the box

5. An ornament piece is made of gold and copper. Its total weight is 96 g. If 1 / 12 of the ornament is copper, find the weight of gold in it.

Solution:

Given

Weight of an ornament = 96 g

Weight of copper = 1 / 12 of 96 g

Weight of copper = 1 / 12 × 96

We get,

= 8 g

Weight of gold = 96 – 8

= 88 g

Hence, the weight of gold in ornament is 88 g

6. A girl did half of some work on Monday and one-third of it on Tuesday. How much will she have to do on Wednesday in order to complete the work?

Solution:

Given

Half of work is done on Monday and one-third on Tuesday by a girl

Let total work done by a girl is 1

Work done on Monday = 1 / 2

Work done on Tuesday = 1 / 3

Hence, remaining work done on Wednesday to complete the work is calculated as below

Remaining work done = 1 – [(1 / 2 + 1 / 3)]

Taking LCM, we get

= 1 – [(3 + 2) / 6]

= 1 – 5 / 6

= (6 – 5) / 6

= 1 / 6

Hence, work done by a girl on Wednesday to complete is 1 / 6

7. A man spends 3 / 8 of his money and 8 still has Rs 720 left with him. How much money did he have at first?

Solution:

Given

Man spends 3 / 8 of his money

Let us assume a man has Rs 1

Amount spent = 3 / 8 of 1

We get,

= Rs 3 / 8

Amount left = 1 – 3 / 8

We get,

= (8 – 3) / 8

= Rs 5 / 8

Since 5 / 8 of his total money = Rs 720

∴ Total money = Rs (720 × 8) / 5

= Rs 5760 / 5

= Rs 1152

Hence, total money a man has is Rs 1152

8. In a school, 4 / 5 of the students are boys, and the number of girls is 100. Find the number of boys

Solution:

Given

Total number of girls = 100

Number of boys = 4 / 5

Let us assume the total number of boys and girls be x

Total number of boys = 4 / 5 of x

We get,

= 4x / 5

According to question, total strength of school can be calculated as below

x – (4x/5) = 100

(5x – 4x)/5 = 100

x = 500

Number of boys = Total strength – Girls

= 500 – 400

= 400

Hence number of boys are 400

9. After finishing 3 / 4 of my journey, I find that 12 km of my journey is covered. How much distance is still left to be covered?

Solution:

Let x km be the total journey

Given that total distance covered = 3 / 4 of the journey is 12 km

According to the question, the distance covered can be calculated as below

3 / 4 of x = 12 km

x = 4 / 3 × 12

x = 4 × 4

x = 16 km

Remaining distance = 16 – 12

= 4 km

Hence, 4 km of distance is left to be covered

10. When Ajit travelled 15 km, he found that one-fourth of his journey was still left. What was the full length of the journey?

Solution:

Let the total journey = x km

Given total distance covered = 15 km

Journey left = 1 / 4 of x

Hence, according to the question, the total distance of journey can be calculated as below

1 / 4 of x = x – 15

x – x / 4 = 15

By calculating further, we get

(4x – x) / 4 = 15

3x / 4 = 15

3x = 60

x = 60 / 3

x = 20

Hence, the full length of the journey is 20 km

11. In a particular month, a man earns Rs 7, 200. Out of this income, he spends 3 / 10 on food, 1 / 4 on house rent, 1 / 10 on insurance and 2 / 25 on holidays. How much did he save in that month?

Solution:

Given

Money earned by a man in a particular month = Rs 7200

Amount spend on food, house rent, insurance and holidays by him are 3 / 10, 1 / 4, 1 / 10 and 2 / 25 respectively

Amount spend on food = 3 / 10 of 7200

= 3 / 10 × 7200

= 3 × 720

= Rs 2160

Amount spend on house rent = 1 / 4 of 7200

= 1 / 4 × 7200

= Rs 1800

Amount spend on insurance = 1 / 10 of 7200

= 1 / 10 × 7200

= Rs 720

Amount spend on holidays = 2 / 25 of 7200

= 2 / 25 × 7200

= Rs 576

Total amount spend = Rs (2160 + 1800 + 720 + 576)

= Rs 5256

Amount saved by man = 7200 – 5256

= Rs 1944

Hence, amount saved by a man in a month is Rs 1944
