$3 {}^{4x - 5} = ( \frac{1}{27} ) {}^{2x + 10} \\ note \: \: that = \\ ( \frac{1}{27} ) = ( \frac{1}{3 {}^{3} } ) = 3 {}^{ - 3} \\ \\ 3 {}^{4x - 5} = (3 {}^{ - 3} ) {}^{2x + 10} \\ 3 {}^{4x + 5} = 3 {}^{ - 3(2x + 10)} \\ equal \: \: bases = > equal \: exponents$

$4x - 5 = - 3(2x + 10) \\ 4x - 5 = - 6x - 30 \\ 4x + 6x = - 30 + 5 \\ 10x = - 25 \\ x = - 2.5$

Dan, Angad & David share some money in the ratio 1 : 1 : 3.

Serhud [2]

<h3>The share of Angad is £ 13</h3>

<em><u>Solution:</u></em>

Given that,

Dan, Angad & David share some money in the ratio 1 : 1 : 3

Let the share of Dan be 1x

Let the share of Angad be 1x

Let the share of David be 3x

In total, Dan and David receive £52

Therefore,

1x + 3x = 52

4x = 52

x = 13

Therefore,

share of angad = 1x = 13

Thus share of Angad is £ 13
