A fruit seller has certain number of oranges. He divides them into two lots A and B. He sells the lot at 3 oranges for Rs. 2 and the lot B at 1 oranges for Rs. 1. Thus he gets Rs. 400, if he had sold the first lot at 1 oranges for Rs. 1 and the second lot B at 5 oranges for Rs. 4, he would have got Rs. 460. Find the total number of oranges. |
Answer» SOLUTION :First of all we make a rough sketch. Let the number of oranges in lot A and B are X and y respectively.  SUBTRACTING equation (1) from (2), we get Subtracting equation (1) from (2), we get 7x = 2100 implies x = 300 Putting x = 300 in equation (1), we get `(2)/(3) (300) + y = 400 impliesy = 200` `therefore`Total number of oranges= x + y = 300 + 200 = 500 |
