9. Meenu sold two chairs for Rs 1200 each, On one chair she incurred a loss of 25%
while on the other she made a profit of 25%, What is her actual gain or loss percent?
Answers
Answer:
short method:- 25×25/100
625/100=6.25%loss
long method:-25%=1/4
cp sp
4 1+4=5
4 4-1=3
total cp=16 and sp=15
difference of cp and sp is 1
1/16×100=100/16=6.25%
Answer:
6.25% loss
Step-by-step explanation:
SP of each chair = 1200
So, for two chairs, total SP = 2400
CP for one chair on which loss incurred:
Loss% = (Loss/CP)*100
Since Loss = CP - SP,
25 = (1 - SP/CP)*100
Substitute SP = 1200.
Now, 25 = (1 - 1200/CP)*100. Solving which, you'll get CP = 1600.
Similarly, for CP of chair on which profit incurred:
Profit% = (Profit/CP)*100
And Profit = SP - CP.
Using the same formulae, we get CP = 960
Adding both, Total CP = 2560.
Total loss since CP>SP, we get = 2560-2400 = 160
Loss% = (Loss/CP)*100
= (160/2560)*100
= 6.25%
Thumb rule: For successive percent profit or loss, use the formula
x + y + (xy/100)
where x and y are percent changes.
+ sign for profit and - sign for loss.
And please remember, whenever same profit and same loss percentage is given, there is always loss.
