<span>1. The problem says that the is ratio 1:3:5 by weight and Talil wants to make 180 kg of concrete mix.
2. Therefore, you have:
1+3+5=9
180 kg/9=20 kg
3. Each of the 9 parts of the ratio weights 20 kg. So, to make 180 kg of concrete mix, he needs:
1x20 kg=20 kg of cement
3x20 kg=60 kg of sand
5x20 kg=100 kg of gravel
4. Talil has:
15kg of cement (Not enough)
85kg of sand (More than enough)
100kg of gravel (Enough)
