Question 1.

An article marked Rs. 800 is sold for Rs. 704. Find the discount and discount percent.

Answer:

M.P = Rs. 800.

S.P = Rs. 704

Discount = MP – S.P = 800 – 704 = Rs. 96

Discount percentage = × 100

= × 100 = 12%

Question 2.

A dress is sold at Rs. 550 after allowing a discount of 12%. Find its marked price.

Answer:

S.P. = Rs. 550

Rate of discount = 12%

Let the marked price be Rs. 100.

Then S.P = 100 – 12 = 88

If S.P. isRs. 88 then the marked price is Rs.100

If the S.P. is Rs. 550 the M.P. is

= 625

Marked price = Rs. 625.

Question 3.

A shop keeper buys a suit piece for Rs. 1400 and marks it 60% above the cost price. He allows a discount of 15% on it. Find the marked price of the suit piece and also the discount is given.

Answer:

C.P = Rs. 1400.

M.P = 60% above the C.P.

M.P = 1400 + 60% of 1400

M.P= Rs. 2240

Discount = Rate of discount × M.P.

Discount = Rs. 336.

Question 4.

A dealer marks his goods 40% above the cost price and allows a discount of 10%. Find the profit percent.

Answer:

Let the cost price be Rs. 100.

Then marked price is 100 + 40 = Rs. 140.

Rate of discount = 10%

If the marked price is Rs.100 the S.P. is 100 – 10 = Rs. 90

If the marked price is Rs. 140 the S.P.

=

∴ C.P. = Rs. 100

S.P. = Rs. 126

S.P > C.P

∴ There is profit Profit = 126 – 100 = Rs. 26

Profit percentage = 26% [∴ C.P. is 100]

Question 5.

A dealer is selling an article at a dis¬count of 15%. Find

(i) The selling price if the market price is Rs. 500

(ii) The cost price if he marks a 25% profit.

Answer:

Rate of discount is 15%

(i) If the M.P. is Rs. 100 the S.P. is 100 – 15 = Rs. 85 So if the M.P. is 500 the S.P. is

85100 × 500

S.P=Rs.425

(ii) S.P. = Rs. 425

Profit % = 25%

The cost price is Rs.340.
