Discount = 1800 - 1230 = Rs. 570
Discount percent = (570/1800) x 100 = 31.67%
Discount percent = (570/1800) x 100 = 31.67%

selling price =sp = Rs 1230
marked price = M = Rs1800
discount% = d
M(100-d)/100 = sp
1800 (100-d)/100 = 1230
100-d = (1230*100)/1800
100-d =1230 /18
100-d =205/3
100 -205/3 =d
do the lcm
(300-205)/3 =d
95/3 =d
d= 31.6 %
marked price = M = Rs1800
discount% = d
M(100-d)/100 = sp
1800 (100-d)/100 = 1230
100-d = (1230*100)/1800
100-d =1230 /18
100-d =205/3
100 -205/3 =d
do the lcm
(300-205)/3 =d
95/3 =d
d= 31.6 %
