Mustafa wants to make 450 kg of concrete mix.
He has 110 kg of cement, 225 kg Of sand and 140 kg of gravel.
Does Mustafa have enough materials to make the concrete mix?

Answer 1

Answer:

first of all 450 kg of concrete mix will be divided in the ratio 2:4:3

we get cement 450/9*2=100 kg

sand 450/9*4=200kg

gravel should be 450/9*3 =150 kg therefore gravel must be 150 kg to prepare concrete
