Vijay had some bananas and he divided them into two lots A and B. He sold the first lot at the rate of ₹ 2 for 3 bananas and the second lot at the rate of ₹ 1 per banana and got a total of ₹ 400. If he had sold the first lot at the rate of ₹ 1 per banana and the second lot at the rate of ₹ 4 for 5 bananas, his total collection would have been ₹ 460. Find the total number of bananas he had.


Let the number of bananas in lot A and B be x and y, respectively

Case I :


Cost of the first lot at the rate of ₹ 2 for 3 bananas + Cost of the second lot at the rate of ₹ 1 per banana = Amount received


…(i)


Case II :


Cost of the first lot at the rate of ₹ 1 per banana + Cost of the second lot at the rate of ₹ 4 for 5 bananas = Amount received


…(ii)


On multiplying in Eq. (i) by 4 and Eq. (ii) by 3 and then subtracting them, we get


(8x + 12y) – (15x + 12y) = 4800 – 6900


- 7x = - 2100


x = 300


Now, put the value of in Eq. (i), we get


2(300) + 3y = 1200


3y = 600


y = 200


Total number of bananas = Number of bananas in lot Number of bananas in lot B = x + y


x + y = 300 + 200 = 500


Hence, he had 500 bananas.
