Ramesh bought two boxes for Rs. 1300. He sold one box at a profit of 20% and the other box at a loss of 12%. If the selling price of both boxes is the same, find the cost price of each box.
Total cost price of two boxes = Rs. 1300
S.P of each box is same.
Let S.P of each box = Rs. 100
S.P of first box = Rs. 100
S.P of second box = Rs. 100
∴ C.P =S.P×100100−Loss%=100×100100−12=1000088
Now ratio in their C.P's
Sum of ratio's = 11 + 15 = 26
∴ C.P of first box =Rs.1300×1126
= Rs. 550
and C.P of second box =Rs.1300×1526
= Rs. 750
