On selling a Mobile for rs750 a shopkeeper looses 10% for what amount should he sell it to gain 5%.


Given: SP= ₹750

Loss= 10%

To do:  Find at what amount  the seller should sell to gain 5%.

Solution:

CP, we can use the formula

CP = $\frac{100}{100-L \%\ } \times SP$

= $\frac{100}{100}-10 \times750$

= $\frac{100}{90} \times750$

= ₹833.34

Now, we need to find new SP for which Gain= 5%

SP= $\frac{100+G\%\ }{100} \times CP$

= $\frac{100+5}{100} \times833$

=$\frac{105}{100}\times833$

= ₹875


So he should sell for Rs. 875
