= 1170
Hence, the Selling Price is Rs 1170.
(ii) In the given question,
Market Price = Rs 500 and discount = 15%

(i) In the question,
Selling Price = Rs 1222 and discount = 6%

= 1300 Rs.
(ii) In the given question,
Market Price = Rs 495 and discount = 1%
∴ Selling Price = 495

(i) In the question,
Market Price = Rs 900 and SP = Rs 873
∴ Market Price = 900
Selling Price = 873

= 90 – 873
= 27
∴ Discount percent (%)
= 27 × 100/900
= 3%
(ii) According to the question,
Market Price = 500
Selling Price = 425
∴ Discount,
= 500 – 425
= 75

= 25%
Question no – (4)

According to the given question,
Market Price = 650
Discount = 3%

Therefore, customer pay for swing machine is Rs 630.50

As per the given question,
Market Price= 720
Selling Price = 684
∴ Discount,

= 36
∴ Discount Percent (%)

= 5%
Question no – (6)
Solution :
According to question,
Selling Price = 720
Discount = 20%
∴ MP = 720 × 100/80
= 900
Thus, the marked price of the saree is 900 Rs.

Solution :
As per the given question,
Selling Price = 555
Discount = 7 1/2% = 15/2
∴ Market Price = 555 × 100 /185/2
= 555 × 100 × 2 /185
= 600
Therefore, the marked price of the article is Rs. 600
Question no – (8)
Solution :
As per the question,
Market Price = 250
Discount = 10%
∴ Selling Price
= 250 × 90/100
= 225 Rs
Profit = 25%
∴ Cost Price
= 225 × 100/125
= 180 Rs
Therefore, the actual cost of article is Rs. 180.
Question no – (9)
Solution :
According to question,
Market Price = 500
Discount = 20%
∴ Selling Price,
= 500 × 80 /100
= 400 Rs
Profit = 25%
∴ Cost Price
= 400 × 100/125
= 320 Rs
Therefore, the actual cost of article is Rs 320.
Question no – (10)
Solution :
Cost Price = 170
Profit = 20%
∴ Selling Price
= 170 × 120/100
= 204
Discount = 15%
∴ Market Price
= 204 × 100/85
= 240
Hence, the marked price of article is Rs. 240
Question no – (11)
Solution :
Let Cost Price = x
∴ Profit = 50%
∴ Selling Price = 150x/100 = 3x/2
Again, Let Market Price = y
∴ Discount = 25%
∴ Selling Price = 75y/100 = 3y/4
According to question,
3x/2 = 3y/4
= x/y = 1/2
∴ x : y = 1 : 2
Hence, the ratio of the Cost Price to the Market Price is 1 : 2.
Question no – (12)
Solution :
Let the advertised price = x
Commission = 23% = 23x/100
∴ After commission Selling Price of Item = x – 23x/100
= 100x – 23x/100
= 77x/100
New profit = 10%
∴ Cost Price = 77x/100 ×10/100
= 77x × 100/ 100 × 100
= 7x/10
According to question,
Selling Price – CP = gain
77x/100 – 7x/10 = 56
or, 77x – 70x/100 = 56
or, 7x = 56 × 100
or, x = 56 × 100/7 = 800
Therefore, his advertised price is Rs. 800
Question no – (13)
Solution :
Let, Cost Price = x
mark at = 40% above on Cost Price
∴ Market Price = 140x/150 = 7x/5
Now discount% = 5%
∴ Discount value = 7x/5 × 5 /10
= 7x × 5/5 × 100
= 7x/100
Given Selling Price = 1064
According to question,
7x/5 – 7x/100 = 1064
or, 140x – 7x/100 = 1064
or, 133x = 1064 × 100
or, x = 1064 × 100 /133 = 800
∴ Cost Price = 800
∴ Selling Price = 1064
∴ Profit = 1064 – 800
= 264
Question no – (14)
Solution :
Given,
profit% = 16%
profit = 48
∴ C.P = profit /profit × 100
= 48/16 × 100
= 300
∴ S.P = 300 × 116/150
= 348
Now, discount = 25%
∴ M.P
= 348 × 100/75
= 464
Question no – (15)
Solution :
As per the question,
M.P. = 275
Discount = 32%
∴ S.P. = 275 × 68/100
= 18700/100
= 187
Therefore, the bookseller pay Rs. 187 for a book.
Question no – (16)
Solution :
Let, C.P = x
Loss = 10%
∴ S.P = 90x/100
Now, discount = 20%
∴ M.P = 90x/100 × 100/80
= 90x × 100 /100 × 80
= 9x/8
∴ Loss = 9x/8 – x
= 9x – 8x/8
= x/8
∴ Loss% = (x/8) / x × 100
= x × 100 / 8 × x
= 12.5%
Question no – (17)
Solution :
Let S.P of fan = x
M.P of table = 480
∴ Discount = 25%
∴ C.P = 480 × 75/100 = 360
Now profit% = 15%
According to question,
x – 360/ 360 = 15/100
or, x – 360 = 15 × 36/10 = 54
or, x = 54 + 360
x = 414
Question no – (19)
Solution :
According to question,
S.P = 660
Profit = 10%
∴ C.P = 660 × 100/110
= 60
∴ Discount = 25%
∴ M.P = 600 × 100/75
= 800
Therefore, the marked price of the item is Rs. 800
Question no – (20)
Solution :
Let, M.P. = x
Discount = 20%
∴ S.P = 80x/100 = 4x/5
Now profit = 20%
∴ C.P = 4x/5 × 100/120
= 4x × 100/ 5× 120
= 2x/3
Given, gain = 360
∴ According to question,
4x/5 – 2x/3 = 360
or, 12x- 10x/15 = 360
or, 2x = 360 × 15
or, x = 360 × 15/2 = 2700
Therefore, the marked price of the cycle is Rs. 2700
Question no – (21)
Solution :
According to the question,
C.P = 1470
Profit = 10%
S.P = 1470 × 110/100
= 1617
Now, discount 12.5%
∴ M.P = 1617 × 10 /87.5
= 1617 × 100/8750
= 1848
Thus, the marked price of a suit is Rs 1848
Question no – (22)
Solution :
Cost Price = 1200
gain = 12%
∴ Selling Price = 1200 × 112/100 = 1344
Now discount = 16%
∴ M.P = 1344 × 100/84 = 1600
Therefore, Aslam should mark Rs. 1600 on a pair of shoes.
Question no – (23)
Solution :
M.P = 850
Discount = 4%
∴ S.P = 850 × 96/100
= 816
Now, profit = 20%
∴ C.P = 816 × 100 /120
= 680
Thus, the cost price of a shirt is Rs. 680.
Question no – (24)
Solution :
In the given question,
M.P = 1120
Discount = 10%
∴ S.P = 1120 × 90/100 = 1008
Now, Profit = 26%
∴ C.P = 1008 × 100/126
= 800
Therefore, the cost price for shopkeeper on pair of shoes is Rs. 800.
Question no – (25)
Solution :
In the question,
MP = 1250
Discount = 10%
∴ S.P = 1250 × 90/100
= 1125
Now, Profit = 25%
∴ C.P = 1125 × 100/125
= 900
Therefore, the cost price of a fan for her is Rs. 900
