800 kg of mortar consists of 55% sand, 33% cement and rest lime. What is the mass of lime in mortar

Solution:

Given, 800 kg of mortar consists of 55% sand, 33% cement and rest lime.

We have to find the mass of lime in mortar.

Total weight of mortar = 800 kg

Percentage of sand = 55%

Percentage of cement = 33%

Percentage of lime = 100 - 55 - 33

= 100 - 88

= 12%

Amount of lime = 12% of 800 kg

= (12/100) × 800

= 12 × 8

= 96 kg

Therefore, the mass of lime is 96 kg.
