Question
800 kg of mortar consists of 55% sand, 33% cement and rest lime. What is the mass of lime in mortar?
Solution
We have,
Percentage of sand in mortar = 55%
Percentage of cement in mortar = 33%
So, percentage of lime in mortar = 100 – 55 – 33 = 100 – 88 = 12%
∴ Weight of mortar = 800 kg
∴ Mass of lime in mortar = 12% of 800 kg
= `12/100 xx 800`
= 12 × 8
= 96 kg
Hence, weight of lime in mortar is 96 kg.
