Hi total gain = 5%
Thus, the amount at the end of 3 years = 100.5 lakh Rupees
The amount he gets from the bank = $$30(1.12)^2 = 42.14784$$ lakh rupees
Let x be the percentage at which he sells the assets of worth 70 lakhs
Thus, the amount he gets = 0.7x lakhs
Thus, 0.7x + 42.1478 = 100.5
Thus, 0.7x = 62.8525
Thus, x is closest to 90
Hence, option C is the correct answer.
