The correct option is A 2000
Given: Simple interest, SI = ₹1,000
Rate of interest, R = 10%
Time period, T = 5 years
To find: The principal amount (P).
We know that S.I. = P×R×T100
⇒P=SI×100T×R
=1000×1005×10
=₹2,000
Therefore, to earn a simple interest of ₹1000, Harish should lend ₹2000 for 5 years.
