Answer 1

Answer:

270

Step-by-step explanation:

See the table where types of Doughnuts and their percentages are shown.

This is the scenario of all types of Doughnuts in the shop at the start of Tuesday.

Now, the sum of cream-filled and maple bacon doughnuts is 81 {As per the condition is given}

Again, from the table, we see that the sum percentage of cream-filled and maple bacon doughnuts is (20 + 10)% = 30%.

Now, if 30% of doughnuts is equivalent to 81 doughnuts, then 100% of doughnuts will be equal to $\frac{81 \times 100}{30} = 270$ doughnuts.

Therefore, there were 270 doughnuts in all in the shop at the beginning of Tuesday. (Answer)
