cost of 75 envelope is ₹637.50
cost of 1 envelope is 637.5/75 = ₹8.5
cost of 23 is 8.5*23 = ₹ 195.5
no. of envelops bought for 800 = 800/ 8.5 = 94.117, but, envelops can only be whole numbers , hence envelope = 94
cost of 94 envelopes = 94*8.5 = 799
therefore , money left = ₹1
cost of 1 envelope is 637.5/75 = ₹8.5
cost of 23 is 8.5*23 = ₹ 195.5
no. of envelops bought for 800 = 800/ 8.5 = 94.117, but, envelops can only be whole numbers , hence envelope = 94
