Question

The sub-triplicate ratio of 2744:3375 is _______

• A. 11:14
• B. 11:15
• C. 14:15
• D. 13:14

Answer 1

The correct option is C

14:15

If a: b is a ratio, then its sub-triplicate ratio is $a^{\frac{1}{3}}:b^{\frac{1}{3}}$

Thus, the sub-triplicate ratio of 2744 : 3375 is ${2744}^{\frac{1}{3}}:{3375}^{\frac{1}{3}}$​​

$\Rightarrow {2744}^{\frac{1}{3}}:{3375}^{\frac{1}{3}}$​​ = 14:15​ ​
