**Sea Shells**

Dhruv lives near the sea. He thought of making necklaces for his three friends. He looked for sea shells the whole day. He collected 112 sea shells by evening. Now he had many different colourful and shiny shells.

He took 28 shells for one necklace.

112-28 = 84

Now he was left with 84 shells. Again he took 28 more shells for the second necklace.

**Try These**

**1. (a) Kannu made a necklace of 17 sea shells. How many such necklaces can be**

** made using 100 sea shells?**

**Ans.** There are 100 sea shells and 17 sea shells are required to make one necklace. So,

Sea shells left after making 1 necklace = 100 – 17 = 83

Sea shells left after making 2 (second) necklace=83-17 =66

Sea shells left after making 3 (third) necklace =66-17 =49

Sea shells left after making 4 (fourth) necklace= 49 – 17 = 32

Sea shells left after making 5 (fifth) necklace = 32 – 17 = 15 .

15 sea shells left after making of 5 necklaces.

So, only 5 necklaces can be made using 100 sea shells. And after making necklaces 15 sea shells will be left unused.

** 250 sacks at a time. How many trips will the truck make?**

**Ans.** In one trip of truck 250 sacks of cement can be carried. The sacks left

= 1500 – 250 = 1250

In second trip of truck another 250 sacks of cement can be carried. The sacks left

= 1250 – 250 = 1000

In third trip of truck another 250 sacks of cement can be carried. The sacks left

= 1000 – 250 = 750

In fourth trip of truck another 250 sacks of cement can be carried. The sacks left

= 750 – 250 = 500

In fifth trip of truck another 250 sacks of cement can be carried. The sacks left

= 500 – 250 = 250

In sixth trip of truck another 250 sacks of cement can be carried. The sacks left

= 250 – 250 = 0

So, he needs six trips of truck to carry all 1500 sacks of cement.

**(d) A driver charges Rs 500 for a trip. How much will Manpreet pay the driver**

** for all the trips?**

**Ans.** Total number of truck trips = 6 For 1 trip driver charges Rs 500.

Therefore, for 6 trips driver charges = Rs 500 x 6 = Rs 3000.

Hence, Manpreet will pay Rs 3000 to the driver for all the trips.
