 Hello and welcome to the session. In this session we will discuss the following question and the question says A man wants to buy 62 shares available at $132, power value being $100. 1. How much will he have to invest? 2. If the dividend is 7.5%, what will be his annual income? 3. If he wants to increase his annual income by $150, how many extra shares should he buy? Let's start the solution now. We will solve part 1 first. In part 1 we have to find how much will he have to invest. We are given that market value of 1 share is $132 and the man wants to buy 62 shares. So the sum invested by the man on the shares is equal to number of shares into market value of 1 share. Now this is equal to number of shares which is 62 into market value of 1 share which is given to be $132. This is equal to $8184. So the answer for part 1 is sum invested is equal to $8184. Now we will solve part 2. In part 2 we have to find his annual income and we are given that dividend is 7.5%. First we will find dividend on 1 share. Now this is equal to 7.5% of the power value which is given to be $100. We write $100. This is equal to 7.5 upon 100 into $100. Zeros get cancelled and this is equal to $7.50. Hence his annual income is equal to total number of shares which is given to be 62. So we have 62 into dividend on 1 share which is $7.50 and this is equal to $465. So the answer for part 2 is annual income is equal to $165. We now move on to part 3. In part 3 we are given that the man wants to increase his annual income by $150. We have to find how many extra shares should he buy. So we can say that since the man wants to increase his annual income by $150 and in part 2 we calculated the dividend on 1 share is $7.50. So we have the income on 1 share is equal to $7.50. Therefore number of extra shares he must buy is equal to the amount by which he wants to increase his annual income that is $150 upon the income on 1 share. Which is $7.50. Now we remove the decimal. So this is equal to $150 upon $750 into $100. This zero gets cancelled and $155 times is $75 and $520 times is $100. So this is equal to $20. So we can say that hence the extra shares to be bought is equal to $20. This is the answer for part 3. With this we end our session. Hope you enjoyed the session.
