Best answer
Correct Answer - Option 1 : Rs. 70,456

Given:

Ratio of amount invested in share market and gold is 6 : 7

Profit earned on the investment after one year is 30%

Ratio of amount reinvested in share market and gold is 4 : 5

Amount reinvested in gold is Rs. 94,500

Calculation:

Since the amount reinvested is in the ratio = 4 : 5

Then total amount reinvested,

⇒ (Amount of gold reinvested × total of ratio)/part of gold in ratio

⇒ (94,500 × 9)/5 = Rs. 1,70,100

Since there was a profit in this amount = 30%

So the Original amount,

⇒ (Total amount reinvested × 100)/130 = Rs. 130846

Original amount invested in gold,

⇒ (130846 × 7)/13

⇒ Rs. 70,455.53 ≈ Rs. 70,456

Original amount invested in gold is Rs. 70,456
