Question

on selling a sofa for rupees 1140 shopkeeper looses 5% how much how much is cost price​

Answer 1

Answer:

cp = (100/100- 5)× 1140

= (100/95 ) ×1140

= 1200

so cost price is 1200

Answer 2

selling price of the sofa =1140

loss percent by selling sofa =5%

Let cost price of sofa =C

selling price={(100-loss%)/100}×C

thus:

(100-5)/100×C=1140

95/100×C=1140

C=1140÷95/100

C=1140×100/95

C=1200
