Answer 1

as we know that

discount % = (discount / sp) × 100

and sp = mp - discount

and discount is always on mp

then

i) mp = 50 , discount % = 2%

discount = 2% of mp

= 2/100 × 50

so discount = rs 1

sp = mp - discount

= 50 - 1 = rs. 49

ii) mp = 210 , discount % = 10%

discount = 10% of mp

= 10/100 × 210

so discount = rs 21

sp = mp - discount

= 210 - 21 = rs. 189

iii) mp = 1200 , discount % = 25%

discount = 25% of mp

= 25/100 × 1200

so discount = rs 300

sp = mp - discount

= 1200 - 300 = rs. 900

iv) mp = 550 , discount % = 12%

discount = 12% of mp

= 12/100 × 550

so discount = rs 66

sp = mp - discount

= 550 - 66 = rs. 484
