cp= 250* 100/100+5

cp= 25000/105

cp= 238

Answer 2

hey mate

here is your answer

3)sp=rs 250

profit =5%

consider cp as x

$x + \frac{5}{100} \times x = 250 \\ \frac{105x}{100} = 250 \\ 105x = 25000 \\ x = \frac{25000}{105} \\ x = 238.09$

4)

$x + \frac{5}{100} \times x = 540 \\ \frac{105x}{100} = 540 \\ 105x = 54000 \\ x = \frac{54000}{105} \\ x = 514.28$

hope it helps u...
