Question No: 17    ( Marks: 2 )

 A man borrows $39000 for 1and half year at a rate of 1.65%. What is the simple interest he has to pay?

Simple interest is given by

I= P*R*T/100

P= principal = $39000

R= interest rate= 1.65%

T= 1.5 year

Interest, I =(39000 * 1.65 *1.5)/100 = Rs 965.25

 

 

 

   

Question No: 18    ( Marks: 2 )

 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.

 

ANSWER:

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

 

 

 

   

Question No: 20    ( Marks: 5 )

 A gold chain is sold for Rs. 6500 at a gain of 25%. Find the profit.

 

Selling price = 6500

Profit = 25%

Profit in Rs= (6500*25)/100= Rs 1625

B-A=  -2      -4           -4       0

          13     -5           -3      14

c)  A+C is not conformable for addition because for addition number of rows and columns of A must be equal to number of rows and columns of C
