Solution
Principal for the month of February = Nil
Principal for the month of March = ₹ 3,100·00
Principal for the month of April = ₹ 2,300·00
Principal for the month of May = ₹ 2,300·00
Principal for the month of June = ₹ 2,300·00
Principal for the month of July = ₹ 3,200·00
Principal for the month of August = ₹ 3,600·00
Total ₹ 16,800·00
(i) If the account is dosed on Sept 29, 1986, then month of Sept., will not earn interest and principal for one month Rs. 16,800.
Rate = 5% p.a.
Interest = ₹`((16,800 xx 5)/(100) xx (1)/(12))`
= ₹ `(168 xx 5)/(12)`
= ₹ 14 x 5
= ₹ 70
(ii) If the account is closed on Oct. 1, 1986
Interest due for the month of September = `("P" xx "R" xx "T")/(100)`
= ₹`((3,600 xx 5)/(100) xx (1)/(12))`
= ₹ 15
∴ Interest due = ₹ (70 + 15) = ₹ 85.
