1). 0.200 m3
2). 0.247 m3
3). 0.274 m3
4). 0.343 m3

The volume of the plaster = 100 m2 × 0.015 m = 1.5 m3
We have to increase the mortar value by (To accommodate new wall depression & wastages volume of plaster)
Increase mortar for uniform wall by 30-35%
For volume of dry mortar increase 25%
So, it is possible to go around 60% extra volume for dry & wet mortar.
Therefore, volume of dry mortar = $(1.5 \times \frac{{160}}{{100}} = 2.4)$
Now 1 part is of cement has 6 part is of sand so,
Cement = (1/7) × 2.4 = 0.343 m3
