12. Tripathi invested Rs $24,000$ and Rs $30,000$ in buying Rs $100$ at par shares of ‘VO’ and ‘HH’ which later declared dividends of $12%$ and $15%$ respectively. After collecting the dividends Tripathi sold the shares as their prices had fallen by Rs $5$ and Rs $10$ respectively. Find Tripathi’s earnings from the above transactions.

From the question it is given that,

Tripathi invested ₹ $24,000$ and ₹ $30,000$ in buying ₹ $100$ at par shares of ‘Vam Organics’ and ‘Hero Honda’.

Then, total investment $=₹24,000+₹30,000=₹54,000$

So, number of shares of ‘VO’ = money invested/cost of one share

$=24,000/100$

$=240$

Number of shares of ‘HH’ = money invested/cost of one share

$=30,000/100$

$=300$

Now, dividend given by ‘V O’ $=12%=(12×24,000)/100=₹2,880$

Dividend given by ‘HH’$=15%=(15×30,000)/100=₹4,500$

Then, total dividend earned $=₹ 2,880+₹4,500$

$=₹7,380$

So, money earned by selling shares of ‘VO’ $=₹95×₹240$

$=₹22,800$

Money earned by selling shares of ‘HH’ $=₹90×₹300$

$=₹27,000$

Therefore, total money earned by selling shares $=₹22,800+₹27,000$

$=₹49,800$

Hence, total earnings = money earned by selling shares + dividends earned

$=₹49,800+₹7,380$

$=₹57,180$

Tripathi’s earnings from the transactions $=₹57,180–₹54,000$

$=₹3,180$
