  1. In what time will ₹8,000, at 3% per annum, produce the same interest as ₹6, 000 does in 5 years at 4 % simple interest ?
    1. 5 years
    2. 6 years
    3. 3 years
    4. 4 years
Correct Option: A

Let Required time = t years
We know that ,

SI =
Principal × Time × Rate
100

6000 × 4 × 5
=
8000 × 3 × t
100100

⇒ 6000 × 4 × 5 = 8000 × 3 × t
∴ t =
6000 × 4 × 5
8000 × 3

t = 5 years
