Use your skill to think as fast as u can to solve ur problems related to any field specially in maths.
F.g. a man gives the discount of 37.5% to the customer & gets 25% profit. if he gives 40% discount then what will be the loss or profit percentage?
Solution: Don't go through methods of percentage directly.
Convert 37.5% into fraction as fast as u can.
It will be 3/8. i.e. he is getting 5/8 of mrp & is equal to 125% because sp=100+25=125 as 25% is the profit.
i.e. he is paying only 4/8 i.e. 50% only.
If now discunt is 40% then he will get 60% of mrp & paying 50% so profit is 10 & will be 20% of 50.
final answer is 20% profit.
Dear stuidents it is necessary to think this as fast as u can so please improve ur speed of thinking for methods to tackle the problems.
thank you
