Question

The loss imcurred by selling a good for Rs.560 isRs.50 more than the profit earned by selling the same good forRs.720 .find out the Cost price of the good

Answer 1

let the profit earned by selling the good at rs 720 be x,

so, cp = 720 - x

in other case the loss is given as 50 more than the profit in first case,
so, loss is x + 50, and cp = 560 + x + 50

now, 
720 - x = 560 + x + 50
720 - x = 610 + x
720 - 610 = x + x
110 = 2x
x = 55

so, cp = 720 - x 
so, cp = 720 -55
so, cp = 665 rs

Answer 2

this is the answer of this question.
