In some questions, to calculate number of debentures issued, we divide total value by issue price. At times we divide it with par value. Which one is right

Solution
To find the number of Debentures issue, we divide the purchase consideration (purchase price) by the issue price. It could be at par, at premium or at discount.
For example..issue issued at par(100), (ii) at premium of rs 10, (iii) at discount of rs 10.
Purchase consideration rs 1,10,000
Number of Debentures issue = 1,10,000/100
1100 debentures
(Ii) number of Debentures = 1,10,000/110
1,000 debentures
(iii) number of Debentures = 1,10,000/90
1,222.22 debentures
