If one-third of one-fourth of a number is 15, then three-tenth of that number is:
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 = |  |
3 | x 180 |  |
= 54. |
| 10 |

Can anyone help me to solve this?
The sum of four numbers is 64. If you add to the first number, 3 is subtracted from the second number, the third is multiplied by 3 and the fourth is divided 3, then the all the results are equal. What is the difference between the largest and smallest of the original numbers?

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.

@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.
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.
