Question 21.

Simplify: .

#### Solution:

Question 22

Write all possible natural numbers using the digits 3, 0, 8. Repetition of digits is not allowed. Also find their sum.

#### Solution:

The given digits are 3, 0, 8 and repetition of digits is not allowed.

The one- digit numbers that can be formed are 0, 3 and 8.

We are required to write 2-digit numbers.

Out of the given digits, the possible ways of choosing the two digits are

3, 0, 3, 8; 8, 0

Using the digits 0 and 3, the numbers are 30.

Similarily, Using the digits 3 and 8, the numbers are 38 and 83.

Using the digits 8 and 0, the numbers are 80.

Hence, all possible 2-digit numbers are 30, 38, 83, 80

Now, We are required to write 3-digit numbers using the digits 0, 3, 8

and the repetition of the digits is not allowed.

Keeping 0 at unit’s place, the 3-digit number obtained are 380 and 830.

Keeping 3 at unit’s place, the 3-digit number obtained are 803.

Keeping 8 at unit’s place, the 3-digit number obtained is 308.

Hence, all possible 3-digit numbers are : 380, 830, 803, 308

All possible numbers using the digits 3, 0 and 8 are :

0, 3, 8, 30, 80, 38, 83, 380, 830, 803, 308.

∴ Sum of all possible numbers obtained using the digits 3, 0, 8

= 0 + 3 + 8 + 30 + 80 + 38 + 83 + 380 + 830 + 803 + 308 = 2563

Question 23

Munna and Munni are aged 14 years and 10 years. Their mother wants to divide ?180 between them in the ratio of their ages. How much does each get?

#### Solution:

The age of Munna = 14 years

The age of Munni = 10 years

Ratio their ages = 14 : 10 = 7 : 5

Sum of their ages = 14 + 10 = 24

Share of Munna = ₹ × 180 = ₹175

Share of Munni = ₹ × 180 = ₹75

Question 24.

Do the ratios 15 cm to 3 m and 15 seconds to 3 minutes form a proportion? Justify your answer.

#### Solution:

3 m = 3 × 100 cm = 300 cm

∴ Ratio of 15 cm to 3 m =

3 minutes = 3 × 60 seconds = 180 seconds

∴ Ratio of 15 seconds to 3 minutes =

As

∴ The given ratio do not form a proportion.

** Section -D**

**Questions 25 to 29 are of 6 marks each.**

Question 25.

To stitch a shirt, 2 m 25 cm cloth is needed. Out of 30 m cloth, how many shirts can be stitched and how much cloth will remain?

#### Solution:

Cloth required to stitch a shirt = 2 m 25 cm

= 2 m + 25 cm

= 2 × 100 + 25 cm

= 225 cm

Total cloth available = 30 m

= 30 × 100 = 3000 cm

Shirts stitched out of 30 m = cm

Hence 13 shirts can be stiched and 75 cm cloth will remain.

Question 26.

Four bells are ringing at intervals of 40, 30, 36 and 45 minutes respectively. At what time will they ring together again if they start ringing simultaneously at 9 A.M.?

#### Solution:

L.C.M. of 40, 30, 36, 45

∴ 2 × 2 × 2 × 3 × 3 × 5 = 360

After 360 minutes or 6 hours i.e. at 3 : 00 P.M.

Question 27.

I bought fruits worth ₹ and vegetables worth ₹. If I gave a fifty-rupee note to the shopkeeper, how much will I get back?

#### Solution:

Question 28.

Javed purchased vegetables weighing 10 kg. Out of this, 3 kg 450 g was potatoes, 2 kg 10 g was onions, 1 kg 750 g was tomatoes and the rest were green vegetables. What was the weight of green vegetables?

#### Solution:

Weight of potatoes = 3 kg 450 g = 3.450 kg

Weight of onions = 2 kg 10 g = 2.010 kg

Weight of tomatoes = 1 kg 750 g = 1.750 kg

Weight of green vegetables = x

⇒ (x + 3.450 + 2.010 + 1.750) = 10 kg

⇒ x = 2.790 kg = 2 kg 790 gm

Question 29

To get a closer finish in a 100 m race, the runners are given different starting positions, depending upon how fast they can run. A starting position of +10 means that the runner starts 10 m in front of the starting line and -5 means that the runner starts 5 m behind the start line. The competitors starting positions are :

Abbas 0 Mohan -3 Rishi -20

Pete + 10 Tarush + 15 Sahel + 5

#####
**(i) Who starts farthest from the finish line?**

**(ii) How far does Tarush have to run to reach the finish line?**

**(iii) How far Mohan has to run to reach the finish line?**

**(iv) How many metres are there between the starting positions of Rishi and Peter?**

**(v) What value is added if the students are asked to run 1 km daily?**

#### Solution:

(i) Rishi starts from the farthest finish line i.e. -20 m is least.

(ii) Starting position of Tarush = +15 Total distance = 100m

Distance covered = 100 – (+15) = 100 – 15 = 85 m

(iii) Position of Mohan = -3 m by Tarush to run to reach the finish line

Total distance he has to cover is = 3 m + 100 m = 103 m

(iv) Starting position of Mike = -20 m

Starting position of Peter = +10 m

Their difference = +10 – (-20) = 30 m

(v) Good for health.
