Question

3. There were five pieces of cloth of lengths 15 m,
21 m, 36 m, 42 m,
48 m. But all of them could
be measured in whole units of a measuring rod.
What could be the largest length of the rod?​

Answer 1

The lengths of the 5 pieces of cloth are 15 m, 21 m, 36 m, 42 m, and 48 m

so,

15 m<21 m<36 m<42 m<48 m

so,

The largest possible length of the rod can be 48 m or greater than 48 m, like 50 m, 55 m, 60 m,etc

Hope this helps you.
