Respuesta :
They share the tips in the ratio 2:5:1.
It means , the total share is 8 ,
that 2 out of 8 is the share of Paul
5 out of 8 is the share of Colin
And 1 out of 8 is the share of Brain
Now total tip = 78.40
Share of Paul = [tex] \frac{2}{8} *78.40 = 19.6 [/tex]
Share of Colin = [tex] \frac{5}{8} *78.40 = 49 [/tex]
And
Share of Brian = [tex] \frac{1}{8} *78.40= 9.8 [/tex]
The difference in their amount will be £29.40
Total amount = £78.40
Paul's share = 2/(2+5+1) × £78.40
= 2/8 × £78.40
= £19.60
Colin's share will be:
= 5/8 × £78.40
= £49
Brian's share will be:
= 1/8 × £78.40
= £9.80
The difference between Colin's amount and Paula will be:
= £49 - £19.60
= £29.40
