1
The average selling price of book B in store 2 and 3 is Rs. 585. What is the selling price of book B in store 2?
» Explain it
D
Let, marked price of book B = Rs. x

Discount in store 2 = 12%

∴Selling price in store 2

⇒Rs.  ( x – x ×  12 )  = Rs. (x – 0.12x) = Rs. 0.88x
100

Discount in store 3 = 8%

∴Selling price in store 3
 
⇒ Rs. ( x – x ×  8 )  = Rs. (x – 0.08x) = Rs. 0.92x
100

According to problem,
 
⇒  1  (0.88x + 0.92x) = 585
2

⇒  1  × 1.8x = 585
2

⇒ 0.9x = 585.
 
⇒ x =  585
0.9

⇒ x = 650

∴Marked price of book B = Rs. 650

∴Selling price of book B in store 2 = Rs.(0.88 × 650) = Rs. 572

Hence, option D is correct.
2
The selling price of book A in store 1 is Rs. 396 and difference of selling price in store 2 and 3 is Rs. 36. What is the discount percentage in store 2?
» Explain it
C
Let, marked price of book A = Rs. x

Discount in store 1 = 12%

∴Selling price in store 1

⇒ Rs. ( x – x ×  12 = Rs. (x – 0.12x) = Rs. 0.88x
100

According to problem,
⇒ 0.88x = 396
⇒ x = 396
0.88

⇒ x = 450

∴Marked price of book A = Rs. 450

Let, discount in store 2 = a%

∴Selling price in store 2
⇒ 450 – 450 ×  a  = Rs. (450 – 4.5a)
100

Discount in store 3 = 24%

∴Selling price in store 3
 
⇒ Rs. ( x – x ×  24 )  = Rs. (x – 0.24x) = Rs. 0.76x = Rs. .76 × 450 = Rs. 342 
100

According to problem,

⇒ (450 – 4.5a) – 342 = 36

⇒ 450 – 4.5a = 378

⇒ 4.5a = 72
 
⇒ a = 72
4.5

⇒a = 16

∴the discount percentage in store 2 = 16%

Hence, option C is correct.
3
By selling book A store 1 makes a profit of 10%. What is the profit/loss percent incurred by store 3 on the same book?
» Explain it
B
Let, marked price of book A = Rs. x

Discount in store 1 = 12%

∴Selling price in store 1

⇒ Rs. ( x – x ×  12 )  = Rs. (x – 0.12x) = Rs. 0.88x
100

Let, cost price of book A = Rs. y

Profit by store 1 = 10%

∴Selling price in store 1
⇒ Rs. (y + y ×    10 )  = 1.1y
100

According to problem,

⇒1.1y = 0.88x

⇒ y = 0.8x

∴Cost price of book A = 0.8x

Discount in store 3 = 24%

∴Selling price in store 3
⇒ Rs. ( x – x × 24 ) = Rs. (x – 0.12x) = Rs. 0.76x
100

∴Loss = Rs.(0.8x – 0.76x) = Rs. 0.04x

∴Loss percentage,
⇒  0.04x  × 100% ⇒ 5%
0.8x

Hence, option B is correct.
4
The average selling price of book D in store 2 and 3 is Rs. 1110. What is the marked price of book D?
» Explain it
A
Let, marked price book D = Rs. x

Discount in store 2 = 6%

∴Selling price in store 2 = Rs. ( x – x ×  6 )  = Rs. 0.94x
100

Discount in store 3 = 9%
∴Selling price in store 3 = Rs.  ( x – x ×  9 )  = Rs. 0.91x
100

According to problem,

⇒ (0.94x + 0.91x) = 1110 × 2

⇒ 1.85x = 1110 × 2
 
⇒ x =  2220
1.85

⇒ x = 1200

∴the marked price of book D = Rs. 1200

Hence, option A is correct.
5
Ratio of discount percentage on book C in store 1 and 2 is 3 ∶ 2. If selling price in store 1 is Rs. 221, then what is the selling price in store 2?
» Explain it
B
Let, marked price of book C = Rs. x

Let, discount percentage on book C in store 2 = a%

Discount percentage on book C in store 1 = 15%

According to problem,

⇒  15  =  3
a 2

⇒ a = 10

∴ discount percentage on book C in store 2 = 10%
 
∴Selling price of book C in store 1 = Rs.  ( x – x ×  15 )  = Rs. 0.85x
100

According to problem,

⇒ 0.85x = 221
 
⇒ x =  221
0.85

⇒ x = 260

∴ marked price of book C = Rs. 260

Discount percentage on book C in store 2 = 10%

∴ Selling price of book C in store 2
= Rs. ( 260 – 260 ×  10 )  = Rs. 234
100

Hence, option B is correct.\
