Answer: Option
Explanation:
Let the number be x.
| Then, | 1 | of | 1 | of x = 15  x = 15 x 3 x 4 = 180. |
| 3 | 4 |
| So, required number = |  |

The one-third = 1\3.
One fourth is = 1\4.
Then, 1\3 + 1\4 + x = 15.
X = 15 * 3 * 4 = 180.
Then the equation is one-third of one-fourth is 15,
The three-tenth number is?
[3\10] * 180 = 54.
[1\3] * 180 = 60.
[1\4] * 180 = 45.
The equation of one third - one fourth = 15.
= 60 - 45 = 15.
Hence, proved the equation 1\3 of 1\4 is 15.
One fourth is = 1\4.
Then, 1\3 + 1\4 + x = 15.
X = 15 * 3 * 4 = 180.
Then the equation is one-third of one-fourth is 15,
The three-tenth number is?
[3\10] * 180 = 54.
[1\3] * 180 = 60.
[1\4] * 180 = 45.
The equation of one third - one fourth = 15.
= 60 - 45 = 15.
Hence, proved the equation 1\3 of 1\4 is 15.

1/3*1/4*x=15
x=15*3/1*4/1
x=180
Therefore required is
=3/10*180
=54
x=15*3/1*4/1
x=180
Therefore required is
=3/10*180
=54
