Question

a man buys a plot for rs 3,00000. he sells 1/3rd at again of 25%. at what price must he sell the remaining land so to make an overall profit of 10%.

Answer 1

over all cost price = 300000

1/3 part sold at 25%

cost price 300000*1/3 = 100000

gain = 100000*25% = 25000

sales = cost price + gain = 100000 + 25000 = 125000...

overall profit and sales required

=sales = cost price + gain

= 300000 + 10% = 330000

amount required to meet this obligation = 330000 - 125000 = 205000

cost of the remaining part = 300000*2/3 = 200000

cost + gain = sales

200000 + gain = 205000

gain = 205000 - 200000 = 5000

gain percentage = gain/cost price = 5000/200000 = 25% is the required gain percentage..
