Solution
Let the production cost of the geyser be Rs x.
Manufacturers gain=6%
Therefore , S.P of the manufacturer=106% of Rsx=Rs.x×106100=53x50
Wholesale dealer's gain=8%
S.P of the dealer=108% of Rs.53x50=53x50×108100
Retailer's gain=10%
S.P of the retailer=110% of Rs.53x50×2725
=53x50×2725×110100
=53x50×2725×1110=15741
⇒x=15741×1011×2527×5053
⇒x=Rs.12500
Hence, the cost of the production of the geyser=Rs 12500
