Answer 1

QUESTION :

A shopkeeper sold a mobile phone for Rs. 12000. Had he offered discount of 10% on the selling price, there would be a loss of 4%. What is the cost price of that Mobile phone?

Step-by-step explanation:

Given that SP = Rs. 12000 - 10%  = Rs. 10,800

Loss% = 4

We know that, C.P = 100/(100 - Loss%) x 100

=> 100/100-4 x 10800

=> 1080000/96

C.P = Rs. 11,250

Answer 2

selling price of phone is rs 5500

Profit = rs 150

so cp = Sp - profit

putting values in above formulae

cp = 5500-150

= rs5350

so cp = 5350
