Question

Ten similar coins were stacked one above the other. When measured with a scale, the readings at the top and bottom were $1.5cm$ and $4cm$ respectively. What is the thickness of each coin?

Answer 1

Step 1: Given Data

Total number of pages $=10$

Reading of top$=1.5cm$

Reading of bottom =$=4cm$

Step 2:Thickness of each coin

Thickness of ten coins $4cm-1.5cm=2.5cm$

Total thickness of one coin $=\frac{2.5cm}{10}=0.25cm$

Hence, The thickness of one coin will be $0.25cm$
