Question

Dylan delivers parcels.

On Thursday, he delivered 10% more parcels than on Wednesday.
On Friday, he delivered 50% fewer parcels than on Thursday.
On Friday, he delivered 77 parcels.
Calculate the number of parcels delivered by Dylan on Wednesday.

Answer 1

Dylan delivered 140 parcels on Wednesday.

Explanation:

On Wednesday:

On Wednesday, he delivered x parcels.

Thursday:

10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x

Friday:

50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.

THis is equals to 77. So

`0.5*1.1x = 77`

`x = (77)/(0.5*1.1)`

`x = 140`

Dylan delivered 140 parcels on Wednesday.
