RBSE Class 5 Maths Solutions Chapter 12 Weight

Practice Work:

Question 1. 
Convert 5 kg in gin.
Solution:
4 kg = gm
4 kg = 1 kg + 1 kg + 1 kg + 1 kg
4 kg = 1 kg + 1 kg + 1 kg + 1 kg
∵ 4 kg = 1000 gm + 1000 gm + 1000 gm + 1000 gm = 4000 gm 

Question 2. 
Convert 3000 gm in kg.
Solution: 
3000 gm = 3 kg
∵ 3000 gm = 1000 gm + 1000 gm + 1000 gm 
= 1 kg + 1 kg + 1 kg = 3 kg

Question 7. 
Ramesh has a weight of 5 kg and 500 grams each. He has to weigh 4 kg 500 gm of sugar. Looking at the scales carefully, tell whether the quantity of sugar kept in the bag will be 4 kg 400 grams or not? 

RBSE 5th Class Maths Solutions Chapter 12 Weight 3
Solution:
Since the bag and weight of 500 grams together make 5 kg equal to the load. Therefore, 500 grams of sugar will be less than 5 kg in the bag, that is, weight of sugar = 5 kg - 500 grams = 4 kg 500 gm.

Question 4.
A shopkeeper sells 250 gm packet of spices by grinding them from 6 kg of spices. Find out the num¬ber of thus formed packets if 4 pack¬ets of 250 gm are prepared from 1 kg of spices.
Solution: 
By grinding 6 kg spicies, we find No. of 250 gm packets as
∵ No. of 250 gm packets in 1 kg = 4 
∴ No. of 250 gm packets in 6 kg = 6 × 4 = 24
Required no. of packets = 24

Question 5. 
If 150 gm of wheat and 100 gm of rice per child is required for the mid day meal, then how much wheat and rice is needed for 60 children?
Solution: 
Per child wheat required = 150 gm
Per child rice Required = 100 gm 
For 60 children required wheat = (60 × 150) gm = 9000 gm
\(\frac{9000}{1000}\) kg = 9 kg
For 60 children required rice = (60 × 100) gm = 6000 gm
\(\frac{6000}{1000}\) kg = 6 kg
Thus, 9 kg wheat and 6 kg rice will required.

= 17 × 200 gm = 3400 gm

(iii) 4\(\frac{3}{4}\) kg = \(\frac{19}{4}\) × 1000 gm
= 19 × 250 gm = 4750 gm

(iv) 2\(\frac{1}{5}\) kg = \(\frac{11}{5}\) × 1000 gm
= 11 × 200 gm = 2200 gm

Question 9. 
Find out:
(i) 1500 gm = ............. kg
(ii) 2250 gm = ................ kg
(iii) 100 gm = ................ kg
(iv) 4750 gm = ................ kg
Solution: 
(i) 1500 gm = 1500 × \(\frac{1}{1000}\) kg
= \(\frac{1500}{1000} \mathrm{~kg}=\frac{3}{2}=1 \frac{1}{2}\) kg

(ii) 2250gm = 2250 × \(\frac{1}{1000}\) kg
\(\frac{2250}{1000} \mathrm{~kg}=\frac{9}{4}=2 \frac{1}{4}\) kg

(iii) 100 gm = 100 × \(\frac{1}{1000}\) = \(\frac{1}{10}\) kg

(iv) 4750 gm = 4750 × \(\frac{1}{1000}\) kg
\(\frac{4750}{1000}=\frac{475}{100}=\frac{95}{20}=\frac{19}{4}=4 \frac{3}{4}\) kg

Short Answer Type Questions:

Question 1. 
If 500 gm flour to required for 1 meal, then how many mean can be prepared by 2 kg flour?
Solution: 
1 kg = 1000 gm 
\(\frac{1}{2}\) kg = 500 gm
By \(\frac{1}{2}\) kg (500 gm) flour = 1 time
By \(\frac{1}{2}\) + \(\frac{1}{2}\) (1 kg) flour = 2 times
Then by 2 kg flour, meal prepared = 2 × 2 = 4 tim
Thus, using 2 kg flour, 4 times meal pre-pared.
