25 Bags of wheat weighing 40 kg costs Rs.2750. Find the cost of 35 bags, if each bag weighs 50 kg?

We'll use the Unitary method to find the cost.

Answer: If 25 bags of wheat weighing 40 kg costs Rs.2750, the cost of 35 bags, if each bag weighs 50 kg is Rs.4812.50.

Let's find the cost of 35 bags if each bag weighs 50 kg.

Explanation:

Given: The cost of 25 bags of wheat weighing 40 kg is Rs.2750.

Let's find the total weight of 25 bags containing 40kg wheat each,

25 × 40 = 1000kg

Therefore, the cost of 1000 kg of wheat = Rs.2750.

Cost of 1kg wheat is = 2750/1000 = Rs.2.75.

Now, 

Let's find the total weight of 35 bags containing 50kg of wheat each,

35 × 50 = 1750kg

Hence, cost of 1750kg of wheat = cost of wheat per kg × 1750

= 2.75 ×  1750

= Rs.4812.50

Thus, the cost of 35 bags of wheat weighing 50 kg each is Rs.4812.50.
