Question

the sum of 55% of a number and 40% of the same number 180.5 what is 80% of that number?​

Answer 1

Step-by-step explanation:

let suppose the number be x

then,

a/q

55%of x+40%of x=180.5

55x/100+40x/100=180.5

95x/100=180.5

95x=180.5×100

so, x=180.5×100/95

therefore, x=190

now,

80%of x=?

80%of 190=?

80%of that number will be 72.
