Answer»

The total number of passed examines is 72%. The number of failure examines is 393.

Then the calculation for total examines is given below.

100% - 72% = 28%

From the given details, 392 are 28% of the total examines.

392 = 28 * x/100

x = 39200 / 28

So the value of x = 1400, which is the total number of examines.

Let the original moped cost be =xA/Qx-5%ofx=15200
