Question

On selling a mobile for rupees 750, a shopkeeper losses 10% . For what amount should he sell it to gain 5%?

Answer 1

SP= ₹750
Loss= 10%
CP = 100/100-L% ×SP
= 100/100-10 ×750
= 100/90 ×750
= ₹833.34
Gain= 5%
SP= 100+G%/100 ×CP
= 100+5/100 ×833
=105/100×833
= ₹875

Answer 2

Answer:

The new selling price of mobile is rupees 875.

Step-by-step explanation:

Let the cost price of mobile be x.

On selling a mobile for rupees 750, a shopkeeper losses 10% . It means

$x-\frac{10}{100}x=750$

$x-0.1x=750$

$0.9x=750$

$x=\frac{750}{0.9}$

$x=833.33$

The cost of mobile is 833.33.

The selling price of phone if gain percent is 5%.

$833.33+\frac{5}{100}(833.33)=874.9965\approx 875$

Therefore the new selling price of mobile is rupees 875.
