A shopkeeper buys a dinner set for ₹ 1200 and marks it 80% above the cost price. If he gives 15 %

discount on it, find:

(ii) the selling price

(iii) his profit percentage Looking to do well in your science exam ? Learn from an expert tutor. Book a free class!

(i) It is given that

C.P. of a dinner set = ₹ 1200

We know that

M.P. = 1200 + 80% of ₹ 1200

By further calculation

= 1200 + 80/100 × 1200

So we get

= 1200 + 80 × 12

By multiplication

= 1200 + 960

= ₹ 2160

(ii) It is given that

M.P. = ₹ 2160

Discount = 15%

We know that

S.P. = (1 – d/100) of M.P.

Substituting the values

= (1 – 15/100) × 2160

By further calculation

= 85/100 × 2160

So we get

= 17/20 × 2160

= 17 × 108

= ₹ 1836

(iii) We know that

Profit = S.P. – C.P.

Substituting the values

= 1836 – 1200

= ₹ 636

Here

Profit % = [Profit/C.P. × 100] %

Substituting the values

= (636/1200 × 100) %

By further calculation

= 636/12 %

= 53 %
