Question

abhay makes a profit of 7% by selling his flat for Rs 642000 at what price should have he have sold it gain 9%

Answer 1

let cost of flat be 100%,profit given as 7%
therefore selling price% is{cost+profit}=107%
given selling price=642000

step 1 is to know cost
therefore,(642000/107)*100=600000 is cost of flat.(by dividing selling price with selling percentage we get price for one percent and we multiply for 100% that we require which is cost)

step2 is to find selling price

selling price=cost+9%{cost}.
sellingprice=600000+600000*9/100=654000
