Answer:
Explanation:
First find the weight of water in the concrete: 15% of 2400kg= 0.15 . 2400kg= 360kg. Now we find the weight of cement, sand and stone in the mixture: 2400kg - 360kg = 2040kg. Let’s find the total parts in the mixture: 1 part(cement) + 2 parts(sand) + 5 parts(stone) = 8 parts. Now we can find the weight of cement, sand and stone: 2040/8 = 255kg.
Weight of cement = 255kg
Weight of sand = 255 . 2 = 510kg
Weight of stone = 255 . 5 = 1275kg
