Question

A number decreased by 15 percent gives 68 the number is

Answer 1

Answer:

No. is 68.15

Step-by-step explanation:

Let the no. be = x

x- 15% = 68

x- 15/100 = 68

100x - 15/100 = 68

100x - 15 = 68× 100

100x = 6800 +15

x = 6815/100

x = 68.15

Answer 2

Answer:

The actual and correct answer = 80

Step-by-step explanation:

Let us make it prove

First of all its a complete number "Y" and also is 100%

so therefore

100% - 15 % X  Y  = 68

85% X  Y = 68

85/100 X Y =68

85Y = 68 X 100

85Y = 6800

Y = 6800/ 85

Y = 80

more proof

68 /80 x 100  = 85 % which is 15 less than 100.

Thank you .
