Question

Kannu made a necklace of 17 sea-shells. How many such necklaces can be made using 100 sea-shells?

Answer 1

Kannu used 17 sea shells to make a necklace.
Number of sea shells used in 1 necklace = 1 ×17
= 17
Number of sea shells used in 2 necklaces = 2 × 17
= 34
Similarly, the number of sea shells used in 6 necklaces = 6 × 17
= 102
So, 102 sea shells are required to make 6 necklaces.
Total number of sea shells available for making necklaces = 100
Thus, Kannu can make 5 necklaces by using 100 sea shells.
