<p>Let the average of four even numbers = A</p>

<p>Four consecutive even numbers</p>

<p>⇒ A − 3, A − 1, A + 1, A + 3</p>

<p>Sum of even numbers = 4A</p>

<p>Let average of five odd numbers = B</p>

<p>Five consecutive odd numbers = B − 4, B − 2, B, B + 2, B + 4</p>

<p>Sum of odd numbers = 5B</p>

<p>Average of odd numbers is 13 more than average of even numbers</p>

<p>⇒ B = A + 13</p>

<p>Sum of odd numbers is 153 more than sum of even numbers</p>

<p>⇒ 5B = 4A + 153</p>

<p>Substitute B = A + 13</p>

<p>⇒ 5(A + 13) = 4A + 153</p>

<p>⇒ 5A + 65 = 4A + 153</p>

<p>⇒ 5A − 4A = 153 − 65</p>

<p>⇒ A = 88</p>

<p>⇒ B = A + 13</p>

<p>⇒ B = 88 + 13</p>

<p>⇒ B = 101</p>
