Answer:

Let

Cost price of cell phone=Rs 100

Marked Price of cell phone=100+\frac{40}{100}\times 100100+

100

40

×100 =Rs 140

Discount=30% of 140

Discount=\frac{30}{100}\times 140=

100

30

×140= Rs 42

Selling price of cell phone=M.P-Discount=140-42=Rs 98

S.P>C.P

Therefore, loss=C.P-S.P=100-98=Rs 2

Loss%=\frac{loss}{C.P}\times 100

C.P

loss

×100

Loss%=\frac{2}{100}\times 100=

Step-by-step explanation:

To find:

Gain or loss percent made by the shopkeeper

Solution:

Let  the cost price of the cell phone = ₹100

Marked Price of cell phone = ₹100+40% of 100

Marked Price of cell phone = ₹140

Discount = 30% of 140

Discount = ₹42

Selling price of cell phone = M.P - Discoun t= ₹140 - ₹42 = ₹98

S.P > C.P

∴ Loss =C.P - S.P = 100 - 98 = Rs 2

Loss% =  $\frac{loss}{cp}$  × 100

Loss% = 2%

Hence, Loss% made by the shopkeeper = 2%
