Answer 2

Given : A certain number decreased by 16 % is equal to 168

To find : The number.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to determine the said number)

Let, the number = x

After getting decreased by 16%, the number will be :

= x - (x × 16%)

= x - (x × 16/100)

= x - (4x/25)

= (25x - 4x)/25

= 21x/25

According to the data mentioned in the question,

21x/25 = 168

x = 168 × 25/21

x = 200

The number is = x = 200

(This will be considered as the final result.)

Hence, the number is 200
