Question

(d) The result of a number, when decreased by
20%, is 192. Find the number.​

Answer 1

Answer:

x=240

Step-by-step explanation:

Let the number be x; then

X - 20% of x = 192

X - (20/100)x = 192

x-(1/5)x = 192

(5 x-1 x) = 960

4x = 960

x= 240

Hence the number is 240

Answer 2

Answer:

x=240

Step-by-step explanation:

Let the number be "x"

x-x*(20/100)=192

x-x*(2/10)=192

10x-2x=192*10

8x=192*10

x=192*100/8

x=240
