QUESTION -

the result of a number when decreased by 20% is 192. find the number?

METHOD TO FIND-

we have to let the total number as x then in the form of equation , we have to solve it also by converting percentage into the number for finding the value of x.

Solution -

let, the total number be x,

then,

(100 - 20 )%

80% of x = 192

80x= 19200

x= 240
