Question 103

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

Answer 1

We have,
Percentage of sand mortar = 55 %
Percentage of cement in mortar = 33 %
So, percentage of lime in mortar = 100 - 55 - 33 = 100 - 88 = 12 %
$\because$ Weight of mortar = 800 kg
$\therefore$ Mass of lime in mortar = 12% of 800 kg $=\frac{12}{100}\times 800=12\times 8=96kg$
Hence, weight of lime in mortar is 96 kg.
