Let the total number of items in the man's shop = y
Number of Brand A's items in the man's shop = y
Remaining items = 1 - y=y
Number of Brand B's items in The man's shop = ofy=y
Total of Brand A and Brand B's items = y+y=y
Number of Brand C's items in the man's shop = 1 - y=y
impliesy = 81 (Given)
impliesy = 81 x 3 = 243
∴ The total number of items in the man's shop = 243
∴ Number of Brand B's items in the man's shop = x 243 = 135
∴ The number of more Brand B items than Brand C = 135 - 81 =54
