Answer:
1008 letters were delivered on Monday
Explanation:
Total mail received = 1344
1/6 were magazines
1/12 were packages
the rest were letters
We have to find the exact number of magazines and packages received
Magazines = 1/6 of the total mail
Magazines = 1/6 × 1344
= 224 magazines
Packages = 1/12 of the total mail
Packages = 1/12 × 1344
= 112 packages
So now that we know the exact number of packages and magazines
We add those two numbers and subtract the result from the total mail
And the remainder is the letters delivered
Magazines = 224
Packages = 112
Magazines + Packages
224+112 = 336
Therefore, the letters received = 1344 - 336
= 1008
Which means that 1008 letters were delivered
