From the following information, calculate interest on Capital of C, a partner for the year ended 31st March, 2022.
C's Capital on 31/3/2022: ₹12,00,000
Profit credited to C for the year ended 31/3/2022: ₹3,00,000
Drawings made during the year: ₹1,00,000
Additional Capital introduced on 1/10/21: ₹5,00,000
Rate of Interest = 12 % p.a.

₹90,000

Opening capital = Closing capital + drawings - Profit - additional capital
                      = 1200000 + 100000 -300000 -500000
                      = 500000
Additional capital = 500000
Interest on opening capital = 500000 X 12/100
                                       = ₹60000
Interest on additional capital = 500000 X 12/100 X 6/12
                                          = 60000 X 1/2
                                          = 30000
Total interest = 60000 + 30000
                   = ₹90000
