Given that,
Cost of 25 bags of wheat weighing 40 kg means total wheat =Rs. 2750
Weight of 25kg bags = 25 X 40 = 1000kg
Hence the cost of 1000 kg wheat is Rs. 2750
Then cost of per kg rice is = 2750/100 = Rs. 27.5
we needto find cost of 35 bags weighing 50 kg means 35 X 50 = 1750 kg
So cost of 1750 kg wheat = 1750 x 27.5 = Rs. 48125
