Answer 1

Given :-

A shop recorded total sales of $ 2000 on Monday .

On , Tuesday its sales fell by 10%

On , Wedenesday sales drop 20% in order to Tuesday

From , Wednesday to Thursday sales increased by an amount equal to 25% of monday's total sales .

Solution :-

According to the question ,

On , Monday total sale = $2000

Now ,

On Tuesday = 10/100* 2000 = $200

Therefore ,

$2000 - $200 = $1800

Hence , The total sale on tuesday is $1800

Then ,

On Wednesday = 20/100 * 1800 = $360

Therefore ,

$1800 - $360 = $ 1440

Hence , The total sale on wednesday is $ 1440

Now ,

On thursday = 25/100 * 2000 = $500

Therefore ,

$1440 + $250 = $1940

Now calculate net change :-

Monday sale - Thursday sale = Net change

$2000 - $1940 = $60

Hence ,

The total net change is $60 .
