Question

A fruit seller losses 10% by selling 26 oranges for 25 rupees. what is the no. of oranges he should for 5 rupees to gain 17%​

Answer 1

$S.p \: of \: 1 \: Orange = rs \frac{25}{26}$

$Loss \: on \: 26 \: Oranges \% = 10\%$

$\frac{C.P - S.P}{C.P } \times 100 = 10$

$\frac{C.P - 25}{C.P } \times 100 = 10$

$C.P - 25 = 0.1C.P$

$C.P \: of \: 26 \: oranges \: = \frac{250}{9}$

$C.P \: of \: 1 \: orange \: =rs \frac{250}{234} = rs \frac{125}{117}$

$require \: profit \: :$

$\frac{5 - C.P2 }{C.P2} \times 100 = 17$

$5 - C.P2 = 0.17C.P2$

$1.17C.P2 = 5$

$C.P2 = rs \frac{5}{1.17}$

$C.P \: of \: 1 \: orange \: : rs1 \frac{125}{117}$

$no. \: of \: oranges \: : \frac{ \frac{5}{1.17} }{ \frac{125}{117} } = 4$

$The \: Answer \: is \: 4$
