and custard puffs are there altogether?​

Answer 1

Answer:

Hi!

Here is the answer to your question.

Let there are x pastries.

Percentage of durain puffs = 49%

Sum of percentages of custard puffs and chocolate puffs = 100 – 49 = 51%

Ratio of chocolate puffs to custard puffs = 5:12

Sum of the parts of the ratio is 5 + 12 = 17

Number of durain puffs = 49 × 6 = 294

Number of custard puffs = 36 × 6 = 216

Thus, number of durain puffs + custard puffs = 294 + 216 = 510
