  \item An organic compound undergoes first-order decomposition. The time taken for its decomposition to $1 / 8$ and $1 / 10$ of its initial concentration are $t _ { 1 / 8 }$ and $t _ { 1 / 10 }$ respectively. What is the value of $\frac { \left[ \mathrm { t } _ { 1 / 8 } \right] } { \left[ \mathrm { t } _ { 1 / 10 } \right] } \times 10 ? \quad \left( \right.$ take $\left. \log _ { 10 } 2 = 0.3 \right)$
