Akhtar , Ben and Carl each have some money akhtar has £65 Ben has £100 Carl has three £5 notes one £20 note and some £10 notes the mean amount of money per person is £80 how many£10 notes does Carl have?

Carl has 4 £10 notes

Step-by-step explanation:

The mean money they have is simply the sum of what they have divided by 3

If we multiplied the mean of what they have by 3, then we have the total of what they have

Let us have the total

Mean is £80 per person; so the total would be £80 * 3 = £240

By adding all they have, we have a total of 240

Let the number of £10 notes Carl has be n

Thus, his total amount would be;

3(5) + 20 + 10(n)

15 + 20 + 10n

= 35 + 10n

Adding what the rest had to it, we have a total of £240

thus, we have it that;

65 + 100 + 35 + 10n = 240

100 + 100 + 10n = 240

10n = 240-100-100

10n = 40

n =40/10

n = 4
