A computer company sells two kinds of computers, A and B, and sold 2200 computers the year before last. Last year, 6% more computers A were sold than the previous year, and 5% fewer computers B were sold. The total sales of the two computers increased by 1 10. How many computers did A and B buy the year before last?

The year before last, computer A sold X and computer B sold (2200-x).

x *( 1+6%)+(2200-x)*( 1-5%)= 2200+ 1 10

x=2000

2200-x=2200-2000=200

I bought 2000 and 200 computers A and B respectively the year before last.

A clothing factory accepts a batch of clothing orders and produces them according to the planned number of days. If 20 sets of clothes are produced every day, the production is less than the ordering task 100 sets; If we produce 23 sets of clothes every day, we will produce 20 sets more than the ordering task. What is the ordering task of this batch of clothes? How many days was originally planned to be completed?

Set the original plan to be completed in x days.

20*x+ 100=23x-20

x=40

20 * x+ 100 = 20 * 40+ 100 = 900

The order task of this batch of clothes is 900 sets, which was originally planned to be completed in 40 days.
