Question 1.
Solve the following word problems.
(a) A uniform set costs ₹ 1,325. What will be the cost of 567 uniform sets?
Solution:
We have to multiply the cost of one uniform by to total number of uniforms, to find the cost.
Cost of 1 uniform set = ₹ 1,325
Cost of 567 uniform sets = 1325 × 567 = ₹ 7,51,275
₹ 7,51,275 is the cost of 567 uniform sets. (b) One packet contains 385 sweets. How many sweets can be packed in 52,690 packets?
Solution:
1 packet contains sweets = 385
52,690 packets contain sweets = 385 × 52,690 = 2,02,85,650
2,02,85,650 sweets can be packed in 52,690 packets.  (c) A rocket travels 7,59,600 km in 240 hours. How many kilometers will the rocket travel in one hour?
Solution:
To find the distance travelled in one hour, we have to divide the total distance by total hours.
In 240 hours a rocket travels = 7,59,600 km
In 1 hour a rocket travels = 759600 ÷ 240 = 3165 km
The rocket travelled 3165 km in one hour. (d) Mr Mohan earns ₹ 19,750 every month. How much will he earn in 8 years?
Solution:
To find his earnings we have to multiply.
In one month he earns = ₹ 19,750
8 years = 12 × 8 = 96 months
In 96 months he earns = 19750 × 96 = ₹ 18,96,000
He will earn ₹ 18,96,000 in 8 years.  (e) During floods, 43,725 villagers became homeless. The government put up tents, each tent housing 265 villagers. How many tents were put up?

Word Problems

We need to multiply and divide in various situations in our daily lives.

Example 1.
Sanjay runs 4,620 meters daily in the morning. How many meters will he run in 1 year? Convert your answer into kilometres.
Solution:
Distance travel in one day = 4,620 m
Distance travel in 365 day = 4,620 × 365 = 16,86,300 m Sanjay runs 16,86,300 meters in one year.
Converting meters into kilometers.
1000 m = 1 km
16,86,300 metre = 1686300 ÷ 1000
= 1686.3 km or 1686 km 3 m Example 2.
A box contains 154 pencils. How many boxes are needed to pack 1,08,878 pencils?
