D Correct answer
Explanation

First, find the original rate: Interest = 740-600 = 140, so rate = (140×100)/(600×5) = 14000/3000 = 4.67%. New rate = 4.67% + 3% = 7.67%. New interest = (600×7.67×5)/100 = 600×0.3835 = 230.1. New amount = 600 + 230.1 ≈ 830. The key is to calculate the original rate first, then add 3% to find the new amount.
