The battery cost =  £0.43

Step-by-step explanation:

Tim buys a torch and a battery . The torch cost 11 times as much as the battery.  

let

cost of battery = a

cost of torch = 11a

The amount he paid is £10 note and he got a change of £4.86. That means he bought both items for 10 - 4.86 = £5.14 .

total cost = a  + 11a

5.14 = a + 11a

5.14 = 12a

divide both sides by 12

a = 5.14/12

a = 0.42833333333

a = 0.428

a ≈ 0.43

The battery cost =  £0.43
