Question 10
CP = 550
profit% =20 and loss%=20
first he sell at 20% profit
SP = 120%of 550
SP = 660Rs
now he sell it at 20% loss
CP=660
SP= 80%of 660
SP =528 Rs
allover he get a loss
loss = 132 Rs
loss% =Loss /CP*100
loss%= 132/660*100
loss%=4%
Here is formula for these types of questions
x = profit%
y =discount%
x+y+(x)(y)/100
In 11th question
x =40%
y =20%
x+y+(x)(y)/100
40+(-20)+(40)(-20)/100
20+(-800)/100
20-800/100
2000-800whole upon 100
1200/100=12%
