Question

Find the difference between 500 reduced by 12% and then by 10% and 500 reduced by 22%. Find the effective reduction percentage in the first case.​

Answer 1

Step-by-step explanation:

500×(1-12%) (1-10%) = 500×.88×.9= 396

500×(1-22%) = 500×.78 = 390

let effective % reduction = x

396 =500(1-x)

1-x = 0.792

x = 1-0.792 = 0.208

x in % form = 0.208×100 = 20.8%

Answer 2

Answer:

20.8

Step-by-step explanation:

440-44 =396

500-110 =390

396-390=6
