Answer:
7.5 kg
Step-by-step explanation:
Ratio of sand to cement = 24kg : 5kg
Today he needs to make the same type of mortar mix, but he will use 36kg of sand.
Let
x = quantity of cement used
Ratio of sand to cement = 36 kg : x kg
Equate both ratios
24 kg : 5 kg = 36 kg : x kg
24/5 = 36/x
Cross product
24 * x = 5 * 36
24x = 180
x = 180/24
x = 7.5
x = quantity of cement used = 7.5 kg
