Answer 2

Answer:

Step-by-step explanation:

If the original number is n

Then the new number after 15% increase= n( 1+15/100) = n x (115/100)

And final number after decrease of 25% = n x (115/100) (1–25/100) = n x( 115/100 ) x (75/100)= (n x 115 x75) /(100 x100)

According to questional

Final number = Original- 22

so (n x 115 x 75)/(100 x 100) = n-22

or, (n x 115 x 75)= (100 x 100 )(n-22)

or. n( 100 x 100 -115 x 75) = 22 x 100 x 100

or, n(10000–8625) = 220000

or, 1375 n = 220000

or, n= 220000/1375= 160

The original number is 160
