Answer:
m.p=rs1800
discount=10%
discount amount=discount%of mp=10/100×1800=rs180
profit=8%
sp=mp-discount=1800-180=1620
cp=sp-profit%ofcp
cp+profit%ofcp=sp
cp+8/100×cp=1620
cp(1+8/100)=1620
cp=1620/1.08=1500
Option 2 is incorrect
-9 is not greater than 4
So -9>4 would be the correct answer
Answer:
Step-by-step explanation:
formula for cylinder:V=πr2h
shape of the base: circle
formula for circle: A=πr2
radius: 6.5cm
height: 16cm
V=3.14x6.5^2x16
2122.64cm^3
Let's suppose the points C, D, E can be anywhere in the interior and BF<10.
If C=A, D=B, E=A we get
|BC|+|CD|+|DE|+|EF| = |AB|+|AB|+|AB|+|FA| = 10 + 10 + 10 + 9 = 39
As the points are in the interior, this won't ever exactly equal 39 so the answer is 38
If BF > 10 then we can actually get a larger answer (thanks Roberto!) so we conclude this isn't the best question ever asked. If it has to be an integer it can't be 19 so it must be 18. Then our maximum is
18 + 18 + 10 + 9 - 1 = 3(18) = 54
