Best answer

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 x 800 

= 12 x 8 

= 96 kg

Hence, weight of lime in mortar is 96 kg.
