**Solution:**

Distance travelled by Victor on Saturday = 89.050 km

Distance travelled by Victor on Sunday = 73.9 km

So the distance travelled more by Victor on Saturday = 89.050 â€“ 73.9 = 15.15 km

Hence, Victor drove 15.15 km more on Saturday.

**8. Raju bought a book for Rs 35.65. He gave Rs 50 to the shopkeeper. How much money did he get back from the shopkeeper?**

**Solution:**

Cost of the book = Rs 35.65

Amount given = Rs 50

So the balance retuned = 50 â€“ 35.65 = Rs 14.35

Hence, the shopkeeper returned back Rs 14.35.

**9. Gopal travelled 125.5 km by bus, 14.25 km by pony and the rest of distance to Kedarnath on foot. If he covered a total distance of 15 km, how much did he travel on foot?**

**Solution:**

Distance travelled by Gopal by bus = 125.5 km

Distance travelled by Gopal by pony = 14.25km

Consider x km as the distance travelled on foot

We know that

Total distance = Distance travelled by Gopal by bus + Distance travelled by Gopal by pony + Distance travelled by Gopal on foot

By substituting the values

150 = 125.5 + 14.25 + x

On further calculation

x = 150 â€“ 125.5 â€“ 14.25

We get

x = 10.25 km

Hence, the distance travelled by Gopal on foot is 10.25 km.

**10. Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?**

**Solution:**

Length of cloth Tina had = 20 m 5 cm = 20.05 m

Length of cloth cut to make curtain = 4m 50 cm = 4.50 m

So the length of cloth left with her = Length of cloth Tina had – Length of cloth cut to make curtain

By substituting values

The length of cloth left with her = 20.05 â€“ 4.50 = 15.55 m

Hence, the length of cloth left with Tina is 15.55 m.

**11. Vineeta bought a book for Rs 18.90, a pen for Rs 8.50 and some papers for Rs 5.05. She gave fifty rupee to the shopkeeper. How much balance did she get back?**

**Solution:**

Cost of book = Rs 18.90

Cost of pen = Rs 8.50

Cost of papers = Rs 5.05

So the total cost = 18.90 + 8.50 + 5.05 = Rs 32.45

Amount given to the shopkeeper = Rs 50

So the balance returned back = 50 â€“ 32.45 = Rs 17.55

Hence, the shopkeeper returned back Rs 17.55.

**12. Tanuj walked 8.62 km on Monday, 7.05 km on Tuesday and some distance on Wednesday. If he walked 21.01 km in three days, how much distance did he walk on Wednesday?**

**Solution:**

Distance walked by Tanuj on Monday = 8.62 km

Distance walked by Tanuj on Tuesday = 7.05 km

Consider x km as the distance walked by Tanuj on Wednesday

It can be written as

Total distance = Distance walked by Tanuj on Monday + Distance walked by Tanuj on Tuesday + Distance walked by Tanuj on Wednesday

By substituting the values

21.01 = 8.62 + 7.05 + x

On further calculation

x = 21.01 â€“ 8.62 â€“ 7.05

So we get

x = 5.34 km

Hence, the distance walked by Tanuj on Wednesday is 5.34 km.

It can be written as

4 7/8Â =Â 4Â +Â 7/8Â =Â 4Â +Â (7Ã—125)/ (8Ã—125)Â

On further calculation

4 7/8Â =Â 4Â +Â 875/1000Â =Â 4Â +Â 0.875Â =Â 4.875

**11. 2+3/10+5/100Â is equal to(a) 2.305(b) 2.3(c) 2.35(d) 0.235**

**Solution:**

The option (c) is correct answer.

We know that 3/10 = 0.3 having denominator as 10, so we need to mark the decimal where 3 is in the tenth place

5/100= 0.05 having denominator as 100, so we need to mark the decimal where 5 is in the hundredth place

It can be written as,

2 + 3/10 + 5/100 = 2+ 0.3 + 0.05 = 2.35

**12. 3/100+5/10000Â is equal to(a) 0.35(b) 0.305(c) 0.0305(d) 0.3005**

**Solution:**

The option (d) is correct answer.

We know that 3/100 = 0.03 having denominator 100, so we mark the decimal where 3 is in the hundredth place

5/10000 = 0.0005 having denominator 10000, so we mark the decimal where 5 is in the ten thousandth place

It can be written as,

3/100 + 5/10000 = 0.03 + 0.0005 = 0.0305

**13. 1 cm is equal is(a) 0.1 m(b) 0.01 m(c) 0.10 m(d) 0.001 m**

**Solution:**

The option (b) is correct answer.

100 cm = 1 m

So we get,

1 cm = 1/100 m = 0.01 m

**14. 1 m is equal to(a) 0.1 km(b) 0.01 km(c) 0.001 km(d) 0.0001 km**

**Solution:**

The option (c) is correct answer.

1000 m = 1 km

1 m = 1/1000 m = 0.001 km

**15. 2 kg 5 gm is equal to(a) 2.5 kg(b) 2.05 kg(c) 2.005 kg(d) 2.6 kg**

**Solution:**

The option (c) is correct answer.

1000 g = 1 kg

So we get 1 g = 1/1000 kg = 0.001 kg

The same way 5 g = 5/1000 kg = 0.005 kg

Hence, 2 kg 5 gm =2 kg + 0.005 kg = 2.005 kg

**16. 15 litres and 15 ml is equal to(a) 15.15 litres(b) 15.150 litres(c) 15.0015 litres(d) 15.015 litres**

**21. Which is greater among 2.3, 2.03, 2.33, 2.05?(a) 2.3(b) 2.03(c) 2.33(d) 2.05**

**Solution:**

The option (c) is correct answer.

We know that the whole parts of all the above numbers are equal.

So by comparing the tenth parts, two of the decimals have a tenth part 0 and two have a tenth part 3.

Now by leaving the decimals which have a tenth part 0, 2.3 and 2.33.

By comparing them, 2.33 is greater than 2.3, where, 2.3 has no hundredth part, while 2.33, the hundredth part is 3.
