Answer 1

Answer:

238.75

Step-by-step explanation:

According to question,

x - 20% of x = 191

So the equation will be,

x - 20/100x = 191

x - x/5 = 191

4x/5 = 191

4x = 191 × 5

4x = 955

x = 955/4

x = 238.75

let then no. be x

then 20% of x= 1/5of x

then according to question

X - 1/5×X = 191 on solving this well get

X=(191×5)/4

X=238.75
