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 = |  |

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.

The question said 1/3 of 1/4 of x is 15.
To get x we need to increase 15 by 4 times, we get 60, and then we need to increase 60 by 3 times to get x.

@Jesvin
X=180
The question said 1/3 of 1/4 of x is 15.
1/4 of 180 is 45
1/3 of 45 is 15.
X=180
The question said 1/3 of 1/4 of x is 15.
1/4 of 180 is 45
1/3 of 45 is 15.

1/3 multiple by x/4 = 15.
X = 180.
3/10. Multiply by 180
gives 54.
X = 180.
3/10. Multiply by 180
gives 54.

(1/3*1/4) * x = 15.
X/12 = 15,
X = 15/12,
X = 180,
3/10 = 180,
= 3 * 18,
= 54.
X/12 = 15,
X = 15/12,
X = 180,
3/10 = 180,
= 3 * 18,
= 54.

@Vishwak.
In Question: three-tenth becomes 3/10 of that number is 180.
So, 3/10*180 = 54.
