Answer 2

Given,

Principal=₹25,000

Amount=₹31,000

Time=2 years

We know ,

1) SI = A-P

So, SI = ₹31,000-₹25,000

=₹6,000

2) SI = ( P×R×T)/100

THEREFORE,

6,000= (25,000×R×2)/100

$or \: 6000 = 250 \times r \times 2$

$or \: \frac{6000}{r} = 500$

$or \: \frac{1}{r} = \frac{500}{6000}$

$or \: r = \frac{6000}{500}$

$or \: r = 12$

Ans: C) R=12%
