If Ramesh wants to earn equal profit by selling shares of NTPC and Unitech, how much more shares of NTPC than Unitech should be sold?
:
C
Let the total number of shares for the month of August 2007 be x and the total profit earned in that month be Rs. Y.
the difference in profit is = Rs.
Selling 20x/100 shares of Unitech earned a profit of Rs.
Selling 10x/100 shares of NTPC earned a profit of Rs.
To earned a profit of Rs. , he should have sold more NTPC shares.
So required percentage = = 66.67%. hence (C)
Alternately:
we can take numbers to calculate: taking data from the first question of this caselet. we have a total of 100 shares and a total profit of Rs. 600.
For NTPC: number of shares=10, profit earned=90
For Unitech: Number of shares=20 , Profit earned=150.
By selling NTPC shares we have to earn Rs.150, then No. of shares sold should be16.66. i.e an increase of 66.66% over 10 shares initially.
