Rohan went to market to buy 10 kg of each of oranges,bananas ,mangoes and grapes.the cost of 5kg of oranges and 2kg of mangoes together was ₹310.the cost of 3kg mangoes and3.5kg bananas together was ₹230.the cost of 1.5kg bananas and5kg grapes together was160.find the total amount spnent by rohan
390+540+160+310= 1400(which is 40kgs in total.)
but i don't understand the reasoning behind 3kg of mangoes + 3.5kg of bananas = 230. when you have taken simply 3.5kg of banana as 230 and 3kg of mango as 230. can you explain the approach to this? what am i missing?3.5kg banana=230 and 1.5kg banana=160 so
5kg banana =230+160=390
3kg mangoes=230,2kg mangoes=310 so
5kg mangoes=230+310=540
5 kg grapes=160
5kg pranges=310 now add up all these
390+540+160+310=1400
