Correct Answer: $\frac{10}{12}$


Solution :
PQ = 12 cm
PR = 13 cm
By Pythagoras theorem, PR 2 = PQ 2 + QR 2
13 2 = 12 2 + QR 2
QR 2 = 169 – 144 = 25
⇒ QR = 5 cm
$\tan P$ = $\frac{5}{12}$
⇒ $\cot R$ = $\frac{5}{12}$
⇒ $\tan P+\cot R$ = $\frac{5}{12}$+$\frac{5}{12}$ = $\frac{10}{12}$
Hence, the correct answer is $\frac{10}{12}$.
