Sagot :
1:11 let’s say 1 = X
So: X:11X
11X - X = 10X = 180
X = 18 (180 : 10)
So total prize is: 18 X 11 = £198
So: X:11X
11X - X = 10X = 180
X = 18 (180 : 10)
So total prize is: 18 X 11 = £198
Answer:
£216
Step-by-step explanation:
The total prize will be the sum of the divisions of the prize. The difference of those divisions is given.
__
divisions
Let P represent the value of the prize. The 1:11 ratio of the parts tells us there are 1 +11 = 12 total parts, and their ratio is P/12 : 11P/12. The sum of these divisions is the whole prize:
P/12 +11P/12 = 12P/12 = P
difference
The difference of the two divisions of the prize is ...
11P/12 -P/12 = £180
10P = £2160 . . . . . . . . multiply by 12 and simplify
P = £216 . . . . . . . . divide by 10
The total prize is £216.

Additional comment
The divisions of the prize are
£216/12 = £18 and 11×£18 = £198
The sum of those divisions is the total prize: £18 +198 = £216.
