Class 10 | Exercise 7D | ICSE | Ratio and Proportion | Selina

Find the value of x, if: (iii) (3x – 7): (4x + 3) is the sub-triplicate ratio of 8: 27.

(iii) (3x – 7): (4x + 3) is the sub-triplicate ratio of 8: 27

And the sub-triplicate ratio of

$\begin{array}{*{35}{l}} 8:\text{ }27\text{ }=\text{ }2:\text{ }3 \\ \left( 3x\text{ }-\text{ }7 \right)/\text{ }\left( 4x\text{ }+\text{ }3 \right)\text{ }=\text{ }2/3 \\ 9x\text{ }-\text{ }8x\text{ }=\text{ }6\text{ }+\text{ }21 \\ x\text{ }=\text{ }27 \\ \end{array}$
