if the manufacturer gains 6% the whole sale dealer 8% and a retailer 10% then what is the production cost of geyser whose retail prices is ₹15741.​

Answer 1

$\large{\sf{\orange{\underline{\underline{Required \:Answer}}}}}$

Let the production cost of the geyser be ₹ x

Manufacturer's gain = 6 %

$∴ \: SP \: of \: the \: manufacture \: = 106\% \: of \: ₹x$

$⠀⠀⠀⠀ = (x \times \frac{106}{100} ) = ₹ \frac{53x}{50}$

Wholesale dealer's gain = 8%

SP \: of \: the \: dealer \: = 108\% \: of \: ₹ \frac{53x}{50}

$= ₹( \frac{53x}{50} \times \frac{108}{100} ) = ₹( \frac{53x}{50} \times \frac{27}{25} )$

Retailer's gain = 10 %

$SP \: of \: the \: \: retailer \: = 110\% \: of \: ₹ (\frac{53x}{50} \times \frac{27}{25} )$

SP \: of \: the \: \: retailer \: = 110\% \: of \: ₹ (\frac{53x}{50} \times \frac{27}{25} )

$= ₹( \frac{53x}{50} \times \frac{27}{25} \times \frac{110}{100} )$

$= ₹( \frac{53x}{50} \times \frac{27}{25} \times \frac{11}{10} )$

But , the retail price is ₹ 15741

$∴ \frac{53x}{50} \times \frac{27}{25 } \times \frac{11}{10} = 15741$

$= > x = \frac{15741 \times 50 \times 25 \times 10}{53 \times 27 \times 11}$

$= 12500$

Hence , the cost if production of the geyser is ₹ 12500
