Paul, Colin and Brian are waiters. One night the restaurant earns tips totalling £78.40. They share the tips in the ratio 2:1:5. How much more does Brian get over Colin? How much more does Colin get over brian

Brian over Colin: £39.20 Colin over Brian: - £39.20

Step-by-step explanation:

The total of ratio units is 2+1+5 = 8. Brian gets 5 and Colin gets 1, so Brian gets (5-1) = 4 ratio units over Colin. Of the total tips, that is 4 of 8 ratio units or 4/8 = 1/2 of the tips:

Brian over Colin = (1/2) (£78.40) = £39.20

The amount Colin gets over Brian is the opposite of this: - £39.20.
