Question

the difference between 36%of a number and 45% of the same number 1342.what is 78% of that number

Answer 1

let the number be x
45x/100-36x/100=1342
45x-36x=134200
9x=134200
x=14912(approx)
therefore 78x/100=78*14912/100=11631

Answer 2

Let the no is x
45/100*x- 35/100*x=1342
X=134200/9
Then
78/100*134200/9=1163.6666...
