Read the following passage carefully and answer the questions.

X Itd. Issued 30,000 shares to the public having Face value ₹100 at 10% premium. Money is receivable as follows:

Application = ₹40 (including premium)

Allotment = ₹45

First and Final call = Remaining amount

The public applied for 50,000 shares. The company rejected application for 10,000 shares and made a pro rata allotment to the rest of the applicants. A shareholder applying for 400 shares, didn't pay the allotment and call money and his allotted shares were forfeited by the company. Later, the forfeited shares were reissued at ₹80 each as fully paid. 

What is the amount of discount per share which is allowed by the company at the time of reissue of forfeited shares?

₹20

The correct answer is option 3- ₹20.

The forfeited shares were reissued at ₹80 each as fully paid. It means ₹100 share is reissued at ₹80 per share.

Discount = 100 - 80
              = 20
