1. Find the S.P. if
(i) M.P. = Rs 1300 and Discount = 10%
(ii) M.P. = Rs 500 and Discount = 15%
Solution:
(i) Given,
M.P. = 1300
Discount = 10%
By using the formulas
SP = Marked price (MP) – Discount
Discount = (MP × Discount %)/100
Discount% = (Discount)/M.P. × 100
By using,
Discount = (MP × Discount %)/100
= (1300×10)/100
= Rs 130
SP = MP – Discount
= (1300 – 130) = Rs 1170
(ii) Given,
M.P. = 500
Discount = 15%
By using,
Discount = (MP × Discount %)/100
= (500×15)/100
= Rs 75
SP = MP – Discount
= (500 – 75) = Rs 425
