Ramesh invested a certain amount in Debit and Equity Funds in the ratio of 5 : 4 respectively. At the end of one year, he earned a total dividend of 30% on his investment. After one year he reinvested the amount including dividend in the ratio of 6 : 7 in Debit and Equity Funds. If the amount reinvested in Equity Funds was Rs. 97,650, what was the original amount invested in Equity Funds?

A Rs. 62,000

B Rs. 8,10,007

C Rs. 60,000

D Rs. 6,50,007

E None of these

Solution

Correct Answer: Option A

∵ the amount invested in Debit and Equity funds is in a ratio 5 : 4,

Amount invested in Debit = 500x

Amount invested in Equity = 400x 

Total invested amount = 900x

According to the question,
He earned a total dividend of 30% on his investment.

Earning as dividend = 30% of 900x = 270x

Given that, Ramesh reinvested including dividend in the ratio of 6 : 7 in Debit and Equity fund.

∴ Total amount of money reinvested = 900x + 270x = 1170x

Now, the ratio of amount invested in Debit and Equity is 6 : 7.

∴ Amount invested in Debit \(= \frac{6}{{6 + 7}} \times 1170x = \;\frac{{6 \times 1170x}}{{13}} = 540x\)

Amount invested in Equity = 1170x – 540x = 630x

Given in question that, the amount reinvested in Equity Funds was Rs.97,650.

So, 630x = 97650

∴ Original amount invested in equity funds = 400x \(= \frac{{97650}}{{630}} \times 400 = 62000\)

∴ Original amount invested in Equity was Rs. 62000.
