Question

if the difference between 75%of a number and 60% of the same number is 82.5 then find 40% of the number​

Answer 1

Answer:

220

Step-by-step explanation:

We take x as the number given in the question.

75% of a number is 75x/100

60% of that same number is 60x/100

So,

75x/100 - 60x/100 = 82.5

》x( 75/100 - 60/100 ) = 82.5

》x = 82.5 ÷ 3/20

》 x = 550

So, the number is 550 and it's 40% will be 220

Answer 2

Answer:

220

Step-by-step explanation:

let the number = a

if the difference between 75%of a number and 60% of the same number is 82.5

75% of a - 60% of a = 82.5

a(75-60) /100= 82.5

a = 82.5 X 100/15

a= 8250/15= 550

40% of the number= 40% of a

= 40 X 550/ 100

= 220
