Question

if the difference between 75% of a number and60% of the same number is82.5 then 20% ofthe number?​

Answer 1

Answer:

number=550

and 20% of 550=110

Step-by-step explanation:

let a number=x

75% of x -60% of x=82.5

(75/100)x - (60/100)x= 82.5

1/100(75x-60x)=82.5

75x-60x=82.5×100

15x=8250

⇒x=550

∴20% of 550=(20/100)×550

                     =110
