Given, Face Value (F.V) for all the shares is 100.
∵ Profit % on M.V = Dividend % on F.V
In 5% at 50, Market value (M.V) = 50
Dividend % = 5 %
⇒ Profit % x 50 = 5% x 100
⇒ Profit % = 10%
In 8% at 120, Market value (M.V) = 120
Dividend % = 8 %
⇒ Profit % x 120 = 8% x 100
⇒ Profit % = 10015 %
= 6.66%
In 9% at 126, Market value (M.V) = 126
Dividend % = 9 %
⇒ Profit % x 126 = 9% x 100
⇒ Profit % = 10014 %
= 7.14 %
In 10% at 160, Market value (M.V) = 160
Dividend % = 10 %
⇒ Profit % x 160 = 10% x 100
⇒ Profit % = 10016 %
= 6.25 %
So the order is 10% at 160, 8% at 120, 9% at 126, 5% at 50.
