In a triangle, if r1=2r2=3r3{r_1} = 2{r_2} = 3{r_3}, then ab+bc+ca\frac{a}{b} + \frac{b}{c} + \frac{c}{a} is equal to
View answer and explanation
Correct option: D
19160\frac{{191}}{{60}}
Option D (19160\frac{{191}}{{60}}) is correct because it's the result of calculating ab+bc+ca\frac{a}{b} + \frac{b}{c} + \frac{c}{a} after finding the ratios of a, b, and c using the given relationship between the exradii.
