A man invests Rs. 5,000 in Rs. 50 shares selling at par. How many shares does he buy?
Answer:
100
When shares are selling 'at par', their Market Value is exactly equal to their Face Value. Here, Market Value = Rs. 50. Number of shares = 5000 / 50 = 100 shares.
192
How many shares of Rs. 100 can be bought for Rs. 7,200 if they are quoting at a 10% discount?
Answer:
80
A 10% discount on a Face Value of Rs. 100 means the Market Value is Rs. 90. The number of shares bought equals Total Investment / Market Value = 7200 / 90 = 80 shares.
193
An investor spends Rs. 8,800 to buy Rs. 100 shares at a 10% premium. How many shares does he acquire?
Answer:
80
A 10% premium on Rs. 100 makes the Market Value Rs. 110. To find the number of shares, divide the total investment by the Market Value. 8800 / 110 = 80 shares.
194
A man invests Rs. 4,500 to buy shares of Rs. 10 at a market value of Rs. 15. How many shares does he purchase?
Answer:
300
The number of shares purchased is calculated by dividing the total investment by the Market Value per share. Number of shares = 4500 / 15 = 300 shares.
195
How much must be invested to buy 300 shares of Rs. 10 at a market price of Rs. 12?
Answer:
Rs. 3,600
Investment depends solely on the Market Value, not the Face Value. Investment = Number of shares × Market Value = 300 × Rs. 12 = Rs. 3,600.
196
Find the total cost of purchasing 80 shares of Rs. 100 each at a 5% discount.
Answer:
Rs. 7,600
A 5% discount on a Rs. 100 share is Rs. 5. The Market Value becomes 100 - 5 = Rs. 95. The cost of 80 shares = 80 × Rs. 95 = Rs. 7,600.
197
How much should a person invest to buy 120 shares of Rs. 100 each at a 10% premium?
Answer:
Rs. 13,200
A 10% premium on a Rs. 100 share equals Rs. 10. Therefore, the Market Value is 100 + 10 = Rs. 110. Total investment = Number of shares × Market Value = 120 × 110 = Rs. 13,200.
198
Calculate the investment required to buy 100 shares of Rs. 50 each at a discount of Rs. 10.
Answer:
Rs. 4,000
When a share is sold at a discount, its Market Value = Face Value - Discount. Market Value = Rs. 50 - Rs. 10 = Rs. 40. The total investment for 100 shares is 100 × Rs. 40 = Rs. 4,000.
199
What is the total investment required to buy 50 shares of Rs. 10 each at a premium of Rs. 5?
Answer:
Rs. 750
When a share is sold at a premium, its Market Value = Face Value + Premium. Market Value = Rs. 10 + Rs. 5 = Rs. 15. The total investment for 50 shares is 50 × Rs. 15 = Rs. 750.
200
A man buys 200 shares of face value Rs. 100 each at a market value of Rs. 120. Find his total investment.
Answer:
Rs. 24,000
To find the total investment, we multiply the number of shares purchased by the market value of each share. Investment = Number of shares × Market Value. Investment = 200 × 120 = Rs. 24,000.
