Question

by selling an article for rs 770,a man incurs a loss of rs 110. find his loss percentage

Answer 1

SP of an article = Rs. 770
loss of an article= Rs. 110
C P of an article = SP + loss
                          = Rs.880
loss percentage = ( loss / C P ) x 100
                           = (110 / 880) x 100
                           =  12.5%

Answer 2

Dear friend,
SP of the article = Rs. 770
Loss = Rs. 110
CP of the article = SP + Loss
= 770 + 110 = 880
Loss % = Loss / CP * 100
= 110 / 880 * 100
= 0.125 * 100 = 12.5 %
So the loss percent is 12.5 %.
Hope it helps you!!
