From the question it is given that,
The number of shares $650$
Then, shares of ₹ $100$ each at a discount of $24% = (100 – 24% of ₹ 100)$
$= 100 – ((24/100) × 100)$
$= 100 – 24$
$= ₹ 76$
So, the investment required to buy $650$ shares $= 650 × 76$
$= ₹ 49, 400$
From the question it is given that,
The number of shares $216$
Then, shares of ₹ $125$ each at par
So, the investment required to buy $216$ shares $= 125 × 216$
= ₹ $27,000$
