Question

A material has a mass of 83 g before abrasion and the abrasive ratio is 1.75. If the area of

abrasion is 23, find the mass after abrasion.

Answer 1

Abrasion ratio= $\frac{175}{100}$

Mass before abrasion= 83g

Mass after abrasion= $\frac{100}{175}\times$ 83g

Mass after abrasion= 47.429g
