The investment ratio of P, Q and R if their profit ratio is 3 : 5 : 7 respectively and their investment time period ratio is 4 : 5 : 6 respectively is :

9 : 12 : 14

6 : 12 : 11

9 : 14 : 12

12 : 9 : 14

✅ Correct Option: 1

Profit $\propto$ Investment $\times$ Time, so Investment $=$ Profit/Time.

P:Q:R $=\frac{3}{4}:\frac{5}{5}:\frac{7}{6}=\frac{3}{4}:1:\frac{7}{6}$ .

Multiply by 12: $9:12:14$ .
