On selling a tea-set at 5% loss and a lemon-set at 15% gain, a crockery seller gains Rs. 7. If he sells
let the cost of tea set and lemon set be x and y respectively.
if he sells a tea set at 5% loss and lemon set at 15% gain.
loss on tea set = x*5/100
gain on lemon set = y*15/100
total gain =
if he sells tea set at 5% gain and the lemon set at 10% gain, total gain = Rs. 13
multiplying eq(1) by 5 and adding eq(2):
substitute y = 80/- in eq(1):
thus the actual price of tea set is Rs. 100 and the price of lemon set is Rs. 80.
hope this helps you.
