Q1: Can a pen of length 450 mm fit inside a box of length 50 cm?
Ans: It is given that the length of the pencil =  450 mm and the length of the box = 50 cm. As both the units are different, we have to first convert 50 cm into mm
We know that,
1 metre = 100 centimetre (cm) or 1 m = 100 cm
1 cm = 10 mm
100 mm = 10 cm
50 cm = 50 x 10mm = 500 mm
As 450 mm is less than 500 mm we can say that the pen will fit in the box.

Q2: A shopkeeper has 150 m of wire and he sold 25 metres of wire to customer A and 30 metres of wire to customer B. What is the length of wire left with him?
Ans: Total length of wire before selling = 150 m
Length of wire sold to customer A = 25 m
Length of wire sold to customer B = 30 m
The total length of wire left = Length of wire before selling - total length sold.
Total length of wire sold = 25 m + 30 m = 55 m
The total length of wire left =  150 - 55 = 95 m
Hence the length of wire left with the shopkeeper = 95 m

Q3: Naseem and Abdul had to fill their pots each with water. Both pots were equally big and heavy so they went to the tap, again and again, filled their bottles and poured water into the pots. Naseem had to fill her bottle 16 times from the tap. But Abdul had to fill his bottle only 8 times. 
(a) Why did Naseem spend more time than Abdul? 
Ans: Naseem had to go more times than Abdul as her bottle was smaller than Abdul's. Abdul had to go only 8 times as his bottle was bigger than Naseem's.
(b) Naseem’s bottle can hold ____ (twice/half/three times) as much water as Abdul’s bottle.
Ans: Naseem's bottle is smaller than Abdul's and can hold half as much water as Abdul’s bottle.

Q4: Pot B holds 11 glassfuls of water. Pot A holds twice as much water as pot B. How many glasses of water are needed to fill pot A?
Ans: It is given that the number of glasses of water pot B can hold is 11 glasses.
Pot A can hold twice as much water as pot B.
The total amount of water Pot A can hold = 11 x 2 = 22
Therefore we can say that pot A can hold 22 glasses of water.

Q5: Aman drinks 9L 750 mL coffee and Raju drinks 7L 800 mL coffee in a week.  How much more coffee does Aman drink than Raju.
Ans: Aman drinks 1L 950 mL coffee more than Raju.
Hint: It is easy to solve this problem if one knows the concept of the capacity of liquids and also how to find the difference between the two capacities given.
Q6: There are two containers of milk. Container A has a total of 10 L 250 mL milk and container B has 8L and 350 mL of milk. Find the total quantity of milk present in both containers.
Ans: Container A and container B have a total of 18L 600 mL of milk in them.
Hint: To solve this problem, students should know the concept of measurement of capacity and how to add two quantities when it's given.

Q7: A shopkeeper sells 12L 500 mL of olive oil on Monday, 3L 200 mL on Tuesday and 14L 200mL on Wednesday. Find the total amount of oil he sold in three days. 
Ans: The shopkeeper sold a total of 29L 900mL of olive oil in three days.
Hint:  To solve this problem, students should know the concept of measurement of capacity and how to add three quantities when it's given.
