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

बेरीज

उत्तर

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.
