A classical case of "homework dumping"

Answer 2

Lets take if..there is 0.39mark-up in 1000...what will be markup in year in %

If 0.39 mark-up in1000
Find X in 100..
So.
1000 0.39
100 X
Cross it we get

0.39/100 and X/1000 lets calculate
39=x/1000 we get 0.039
Now as in qusetion we have to calculte per annum so multiply it with 365
0.039×365 we get (14.235%) thanks

to solve this more quickly,

= 0.39/1000
= 0.0039
Multiply it with 365
=0.0039 x 365
= 0.14235
