Answer 1

this is the answer of the question

Answer 2

I gain 4 % by selling it for a 1040

Solution:

Given that,

Selling price = Rs 950

Loss % = 5 %

Find the cost price

$Cost\ price = \frac{100}{ 100 - loss \% } \times SP\\\\Cost\ price = \frac{100}{ 100 - 5 } \times 950\\\\Cost\ price = \frac{100}{ 95 } \times 950\\\\Cost\ price = 1000$

What percent shall i gain by selling it for a 1040?

SP = 1040

CP = 1000

Gain % = ?

Gain = SP - CP

Gain = 1040 - 1000

Gain = 40

Find gain percent

$Gain\ percent = \frac{ gain } {CP} \times 100\\\\Gain\ percent = \frac{40}{1000} \times 100\\\\Gain\ percent = 4 \%$

Thus, i gain 4 % by selling it for a 1040
