Let the number be"x"
Here the ques clearly says that,
One third=1/3.
One fourth=1/4.
One-third of one-fourth of a number is 15.
i.e 1/3*1/4*x=15(in between one third and one fourth "of" is there."of" indicates multiplication(*)).
Now,
1/12*x=15.
x=12*15.
x=180.
Now he is asking three tenth number
3/10*x=3/10*180=54.
Thats it. Those who didn't understand make a comment.

Why the number 180 is multiplied by (3/10)?
And why 10?
And why 10?

@R.Mohana Jayanti.
One third of one fourth means = 1/3*1/4 = 1/12.
In problem they given that one third of one fourth is equal to 15.
So 15 = 1/12.
= 12*15.
= 180.

Go from answer to question !
If we take 54 it is 3/10 then divide 54 by 3 i.e. 54/3 =18*10=180.
If we take 54 it is 3/10 then divide 54 by 3 i.e. 54/3 =18*10=180.

Here we are asked to find the 3/10 of the number. The number obtained is 180. So 3/10*180.
