whenever we have an amount to be divided in ratios, we simply divide the total amount by the sum of those ratios and then distribute accordingly.  In this case, let's divide 77.40 by (1+3+5) and then distribute accordingly to each chap.

\bf \stackrel{Paul}{1}~~:~~\stackrel{Colin}{3}~~:~~\stackrel{Brian}{5}~\hfill \cfrac{77.40}{1+3+5}\implies 8.6 \\\\\\ \stackrel{Paul}{1\cdot 8.6}~~:~~\stackrel{Colin}{3\cdot 8.6}~~:~~\stackrel{Brian}{5\cdot 8.6}\qquad \implies \qquad \stackrel{Paul}{8.6}~~:~~\stackrel{Colin}{25.8}~~:~~\stackrel{Brian}{43} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{Brian get this much more than Paul}}{43-8.6\implies 34.4}~\hfill

Answer:

£34.40

Step-by-step explanation:

Paul, Colin and Brian are waiters.

One night the restaurant earns tips totalling £77.40

They share the tips in the ratio 1:3:5

Paul gets \frac{1}{9} × £77.40 = £8.60

Brian gets \frac{5}{9} × £77.40 = £43.00

Brian gets £43.00 - £8.60 = £34.40 more than Paul.

Answer:

The correct answer is third option

JK and LM meet at a right angle.

JK and LM are two line segments.

If two line segments are perpendicular to each other means that two lines are intersecting each other making angle 90°

Here JK ⊥ LM therefore JK and LM meet at a right angle.
