Simple interest is given by

I= P*R*T/100

P= principal = \$39000

R= interest rate= 1.65%

If

Cost price = 2000Rs

Selling price = 6500Rs

Then what will be %Markup on cost?

MUC= S- C (Rs markup on cost = selling price- cost price)

= 6500-2000 = Rs 4500

% markup on cost = (MuC/cost price) * 100 = (4500/2000) *100=  225%

Question No: 19    ( Marks: 3 )

Write the output of B9, B10, B11 and B12. If you think the formula is incorrect write "Error" in output.

The output of =sum(B3,B4,B5,B6) = 100

=multiply(B5,B6) will not give result because multiply is not a excel function

B4/B6 is not a formula because in excel formula must start with "="

=B4% will return 0.2
