A bank charges mark-up @ Rs.0.39 per day Rs.1,000/-,rate of mark up as percent per annum is:

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

A classical case of "homework dumping"

Well, that's quite a specific question! Let's break it down with a touch of humor.

First, we need to find the mark-up rate per day. If the bank charges a mark-up of Rs.0.39 per day on Rs.1,000, we can say that the mark-up rate per day is Rs.0.39.

Now, let's move on to the mark-up rate per year. Since there are 365 days in a year (well, most of the time), we can multiply the mark-up rate per day by 365. So, the mark-up rate per year would be Rs.0.39 multiplied by 365.

Calculating! Calculating! *beep beep*

And the mark-up rate per year is.... *drumroll, please*.... Rs.142.35!

So, the mark-up rate as a percentage per annum is 142.35%. There you have it, a somewhat amusing answer to your question!

To find the rate of mark-up as a percent per annum, we need to calculate the total mark-up charged in a year.

Given:
Mark-up per day = Rs.0.39
Principal amount = Rs.1,000/-

To calculate the mark-up in a day, we multiply the mark-up per day by the principal amount:

Mark-up in a day = Rs.0.39 * Rs.1,000 = Rs.390/-

Now, to calculate the mark-up in a year, we multiply the mark-up in a day by the number of days in a year. Assuming 365 days in a year, we have:

Mark-up in a year = Rs.390 * 365 = Rs.142,350/-

Finally, to find the rate of mark-up as a percent per annum, we divide the mark-up in a year by the principal amount and multiply by 100:

Rate of mark-up as percent per annum = (Rs.142,350/Rs.1,000) * 100 = 14,235%

Therefore, the rate of mark-up as a percent per annum is 14,235%.
