Answer 1

${\huge{\underline{\large{\mathbb{\red{ We have,</p><p>Rate = 4 % per annum</p><p>CI = ₹163.20</p><p>Principal (P) = Rs 2000</p><p>By using the formula,</p><p>CI = P [(1 + R/100)n – 1]</p><p>Substituting the values, we have</p><p>163.20 = 2000[(1 + 4/100)n – 1]</p><p>163.20 = 2000[(1.04)n -1]</p><p>163.20 = 2000 × (1.04)n – 2000</p><p>163.20 + 2000 = 2000 × (1.04)n</p><p>2163.2 = 2000 × (1.04)n</p><p>(1.04)n = 2163.2/2000</p><p>(1.04)n = 1.0816</p><p>(1.04)n = (1.04)2</p><p></p><p>So on comparing both the sides, n = 2</p><p>Therefore,</p><p>Time required is 2 years.</p><p>Hopes this helps you ✌☺}}}}}}$
