<p><strong>Investment 1:</strong></p>

<p>Principal: 15000</p>

<p>Rate: 10%</p>

<p>Time: 2 years</p>

<p>Amount: 15000 × (110/100)<sup>2</sup> = 18150</p>

<p><strong>Investment 2:</strong></p>

<p>Principal: 10000</p>

<p>Rate: 8%</p>

<p>Time: 2 years</p>

<p>Amount: 10000 × (108/100)<sup>2</sup> = 11664</p>

<p><strong>Investment 3:</strong></p>

<p>Principal: 20000</p>

<p>Rate: 5%</p>

<p>Time: 2 years</p>

<p>Amount: 20000 × (105/100)<sup>2</sup> = 22050</p>

<p>Now,</p>

<p>Total principal = 15000 + 10000 + 20000 = 45000</p>

<p>Total amount (after 3 years) = X = 18150 + 11664 + 22050 = 51864</p>

<p>Putting it into compount interest formula:</p>

<p>X = principal × ((100 + rate)/100)<sup>time</sup></p>

<p>i.e.</p>

<p>51864 = 45000 × ((100 + rate)/100)<sup>1</sup></p>

<p>1.152 = ((100 + rate)/100)<sup>1</sup></p>

<p>(100 + rate)/100 = 1.152</p>

<p>100 + rate = 115.2</p>

<p>rate = 15.2%</p>
