Correct option is (C) ₹ 2400
Let originally Ravi has Rs x.
\(\therefore\) After spending 75% money, the left money
= Rs (x - 75% of x)
= Rs (x - \(\frac{75x}{100})\) = Rs (x - \(\frac{3x}{4})\) = Rs \(\frac x4\)
\(\therefore\) \(\frac x4\) = 600 (Given)
\(\Rightarrow\) x = 600 \(\times\) 4 = 2400
Thus, Ravi has Rs 2400 originally.
