Ответ:
Below in bold.
Step-by-step explanation:
The total sum of the numbers in A is 124 and the sum of the numbers in B = 56
Let x be the number passed from A to B, then from the given information:
124 - x = 56 + x + 20
124 - 56 - 20 = 2x
48 = 2x
x = 24.
a) So the number passed is 24.
b) Sum of numbers in B = 56 + 24 = 80.
c) Let pencil cost x then pen will cost 1.1 - x.
Now the pen costs 1 pound more than the pencil
so 1.1 - x - x = 1
-2x = -0.1
x = 0.05.
So the pen costs 1.1 - 0.05 = £1.05.
