Answer 2

Explanation:

hello friend here is your answer:

let the cost of the mobile phone be rs.x

since the shop keeper lost 10%

.°. S.P = x - (10% of x)

$= x - \frac{10x}{100} \\ = x - \frac{x}{10} = \frac{9x}{10} \\ but \: sp = rs750 \\ = \frac{9x}{10} = 750 \\ or \: x = \frac{750 \times 10}{9} = rs.833.33 \\ the \: price \: of \: the \: phone \: is \: rs \: 833.33 \\ the \: new \: sp = 833.33 + 5\% \: of \: rs833.33 \\ = rs(833.33 + \frac{5 \times 833.33}{100} ) \\ = 833.33 + 41.667 = rs.874.997$
