Question

A sells a watch to B at a gain of 20% and B sells it to C at a loss of 10% and C sells it for rs 1404,gaining 4%.How much did A pay for it?

Answer 1

Answer:

rs 1250

Step-by-step explanation:

let cost price for A = 100%

gain for A = 20%

cost price for B = Selling price for A = 100%+20% = 120%

loss for B = 10% of 120% = 10×120/100 % = 12%

cost price for C = Selling price for B = 120%-12% = 108%

gain for C = 4% of 108% = 4×108/100 % = 4.32%

Selling price for C = 108%+4.32% = 112.32%

given, 112.32% = 1404

=> 100% = 1404×100/112.32 = rs 1250

so cost price for A = rs 1250
