Question

the cost of 25 bags of cement each weighing 40 kg is rupees 2750 what is the cost of 45 bags of cement is weighing 36 kg​

Answer 1

Total amount of cement in kg = 25 × 40 = 1000

Total cost of 1000 kg cement = 2750

Cost of 1 kg of cement = 1000 ÷ 2750 = 0.36

We need to find,

Cost of 45 bags of cement with 26 kg each

Total amount of cement in kg = 45 × 36 = 1620

Cost of 1620 kg of cement = 1620 × 1 ÷ 0.36

= 4500

So the cost of 45 bags of cement is 4500
