Question

A bakery sells taro, red bean and green tea pues. 65% of the pies are taro pies. 40% of the remaining pies are red bean pies. How many pies are there altogether?​

Answer 1

Answer: 1,800 pies in total

Explanation:

A key detail missing is that there are 378 green tea pies.

Assuming the total number of pies is x.

65% of this is taro pies. This leaves 35% to be red bean pies and green tea pies.

If 40% of this remaining 35% are red bean pies, that means that 60% are green tea pies.

= 35% * 60%

= 21% of the total are green tea pies

There are 378 green tea pies and this is 21% of the total number of pies.

378 = 0.21 * x

x = 378 / 0.21

= 1,800 pies in total
