<p>10 years ago:</p>

<p>Total = 45x</p>

<p>Present total (no change case) = 55x</p>

<p>Old principal present age = 60 + 4 = 64</p>

<p>New principal present age = 54 + 3 = 57</p>

<p>Loss = 64 − 57 = 7</p>

<p>Actual total = 55x − 7</p>

<p>Given:</p>

<p>(55x − 7)/x = 55 − 0.28</p>

<p>54.72 = 55 − 7/x</p>

<p>7/x = 0.28</p>

<p>x = 7 / 0.28 = 25</p>
