@Dhivya.

How did you compare 50/3x = 64*1500.
you mentioned in the above equation that;
50/3*64.

1500*x
therefore,50/3*64 =1500*x,
this might be possible.
Then how did you declared that comparison? Please explain to me.

@All.

Solve it by logic;

For earning rs.50/3 he has invested Rs.64.
To earn Rs.1500 how much thus he had to invest,
50/3. 64.
1500. x.

50/3x = 64 * 1500.
Therefore:
x = 64 * 1500 * 3/50.
Ans : 5760.

Hope this might help.

Isn't is 50/3 when investing 100?

So the profit when 64 is invested is 64*50/300?

Shivansh said:   2 years ago
Let's say person earn X% When he invest Rs 64 which comes out to be Rs 50/3
64 * x% = 50/3.
Now you can find x value correct which is 3.8% so now find 38% of 1500= 5760.

The profit is 50/3 on investing 64.
The profit is 1500 on investing X.

Therefore, (50/3) / 64 = 1500 / X.
Hence X = 64 * 3/50 * 1500.

Yes, you are right the face value is assumed to be 100.

I believe here ideally the Face Value should have been mentioned, the face value assumed is 100.

Total Investment= ((Total Income)/(Face Value * Dividend ) ) * Market Value

Please take a note Market Value is Investment per share.

50/3 rs at 64 ,
Then 1500rs at = 64/(50/3) * 1500.
=> 64 * 3 * 1500/50.
=>64 * 90,
=>5760.

"Earning" here implies dividend on the total face value of the stocks (and NOT on the investment amount).
