Let's simplify ~




Therefore, A is the Correct choice !
Step-by-step explanation:
I think you mean you want to find out 40% of a number,, when 60% of it is 180, so I'll answer that:
60% = 180
÷6
10% = 30
x4
40% = 120
(if you want to find 100%, multiply 30 by 10)
Hopefully this helps :)
The given equation is,

Thus, option (C) is the correct solution.
Divide each side of the equation by 0.3 .
The discount is 65%
