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

Percentage of sand in motar = 55%


Percentage of cement in motar = 33%


Percentage of lime in motar = 100-55-33


= 100-88 = 12%


∴ Weight of motar = 800kg


∴ Mass of lime in mortar = 12% of 800kg


= × 800


= 96kg
