The ratio of three numbers is $\frac{1}{4}: \frac{5}{6}: \frac{1}{3}$ respectively. If the sum of the number is 68, what is the value of $\frac{1}{3}$ of the first number? |
6 8 2 4 |
4 |
Here, \(\frac{1}{4}\) : \(\frac{5}{6}\) : \(\frac{1}{3}\) ⇒ Take LCM 12, ⇒ 3 x 1 : 2 x 5 : 4 x 1 = 3 : 10 : 4 ⇒ (3 + 10 + 4) units = 68 ⇒ 17 units = 68 ⇒ 1 unit = 4, ⇒ $\frac{1}{3}$ of 1st number 3 = 3 x 4 = 12 x $\frac{1}{3}$ = 4. |
