Answers
the solution is an example of your question seeing this try to solve yours
Short trick:-
Number of articles / what needs to be done X what has already been done.
According to the question,
Number of articles =6(toffees)
What needs to be done = 150% (100%+50% profit)
What has already been done = 100%(nothing is given related to loss and profit so assume it 100%)
Therefore,
6/150 X 100 = 4 toffees
Similarly you can solve the other questions of the same pattern:-
By selling toffees at 45 for a rupee, a man loses 8%. How many toffees must he sell for a rupee in order to gain 15%?
SOL) Number of articles = 45
What needs to be done = (100%+15%) = 115%
What has already been done = (100%-8%) = 92%
Therefore,
45/115 X 92 = 36 toffees , which is the required answer.
I hope it helps.
