Answer 1

Answer:

Step-by-step explanation:

No. of sales of A in a year = 52 (approx.)

No. of sales of B in a year = 91 (approx.)

No. of sales  Of B more than A = 91 - 52 = 39 days

Now these extra sales of B can be put together with A = 365 / 39 = 9 (Approx.)

∴ There will be 9 days of sale of 'A' and 'B' together
