The correct answer is option 3- (A)-(II), (B)-(III), (C)-(I), (D)-(IV).
List-1
(Interest on Drawings)
|
List-II
Time (Month)
|
| (A) When the amount is withdrawn at the beginning of each month |
(II) 6.5 months |
| (B) When the amount is withdrawn at the end of each month |
(III) 5.5 months |
| (C) When the amount is withdrawn at the middle of each month |
(I) 6 months |
| (D) When the amount is withdrawn at the end of each quarter |
(IV) 4.5 months |
(A) When the amount is withdrawn at the beginning of each month-(II) 6.5 months.
Ist drawing = 1st April, so months left after it are 12.
Last drawing = 1st March, so months left after it are 1.
Average Period = (No. of months left after 1 drawings + No. of months left after last drawings)/2
= (12+1)/ 2
= 6.5 months
(B) When the amount is withdrawn at the end of each month-(III) 5.5 months.
Ist drawing = 30 April. So, months left after ist drawing is 11.
Last drawing = 31 March. So, months left after last drawing is 0.
Average period = (Months left after ist drawings + Months left after last drawings)/2
= (11+0)/2
= 11/2
= 5.5
(C) When the amount is withdrawn at the middle of each month-(I) 6 months.
Ist drawings = 15 April. Months left after it is 11.5
Last drawing = 15 March. Months left after this is 0.5
Average Period = (No. of months left after 1 drawings + No. of months left after last drawings)/2
= (11.5+0.5)/ 2
= 6 months
(D) When the amount is withdrawn at the end of each quarter-(IV) 4.5 months.
Ist drawing = 30th June, so months left after it are 9.
Last drawing = 31st March, so months left after it are 0.
Average Period = (No. of months left after 1 drawings + No. of months left after last drawings)/2
= (9+0)/ 2
= 4.5 months |
