If the rate of simple interest is 12% per annum the amount that would fetch interest of Rs 6000 per annum is?

Rate of Interest = 12% per annum
Simple Interest =Rs 6000 per annum
Let 'P' is the principal
SI= (P x R x T)/100
where , SI= Simple Interest
T= Time
R= Rate
∴ 6000=(P x 1 x 12)/100
∴ P =(6000 x 100)/12
= Rs 50000
Hence the required amount is Rs 50000
