Answer 1

3/5 of x =168
3x/5=168
3x =168×5
3x=840
x =840/3
x=280
12% of x=280
=12/100×280
=33.6

Answer 2

Given:

Three-fifth of the number is 168

To find:

12% of that number

Solution:

The required 12% of the number's value is 33.6.

Let the number be A.

We are given that 3/5 of this number is equal to 168.

So, we will obtain its 3/5th and equate it with 168.

Using values,

3/5 of A=168

3/5×A=168

On solving, we get

3A=168×5

A=168×5/3

A=56×5

A=280

Now, we have to get 12% of A.

So, 12 % of A=12/100×280

=12/10×28

=6/5×28

=33.6

Therefore, the required 12% of the number's value is 33.6.
