They withdrew some amount from the firm for their personal use. Partnership deed provide interest on drawings @10% p.a. but no interest on capital. Market rate of interest on capital in similar firm is 5% p.a. C also gives a loan of ₹1,00,000 to the firm without any agreement of interest whereas market rate of interest on loan is 12% p.a.

What will be the interest on drawings if B withdraw ₹90,000 in the middle of each quarter?

₹18,000

The correct answer is option 1- ₹18,000.

Total drawings = 90,000 x 4
                        = ₹3,60,000

Average period = (10.5+ 1.5) / 2
                         = 6 months

Interest on drawings = 3,60,000*6/12*10/100
                                  = ₹18,000
