How much did Rohit borrow? I. Rohit borrowed at 10% per annum SI from Rakesh; returns after 5 years. II. Rakesh returns 5% of the total amount received = ₹240.

Statement I alone is sufficient
Both statements together are needed
Statement II alone is sufficient
Either statement alone is sufficient

Correct answer: Both statements together are needed

Solution

I alone: SI rate×time = 10%×5 = 50%. Total returned = 1.5P. Cannot find P without total. II alone: Total received = 240/0.05 = ₹4800. Cannot find P without rate+time. Together: 1.5P = 4800 → P = ₹3200. Both needed.
