Answer 1

This Solution is very easy. Here is it.

Step-by-step:

length of string = 8 m or 800 cm

width of cardboard = 15 cm

length of string req. for 1 winding = width × 2

= 15×2 = 30 cm.

No. of Windings = 800/30 = 80/3

on dividing 80 by 3, we get,

Quotient = 26

Remainder = 2

Answer:

Therefore, No. of windings are = 26 times.

and, The length of remaining string = 2 cm.
