ANSWER ::

Cos (A+B) = 0

A+ B = 90° - - - - - - - - - - - (1)

AGAIN

Cos (A-B) = √3 /2

A - B = 30° - - - - - - - - - - - - (2)

FROM (1) & (2)

ON ADDITION

2A = 120°

A = 60°

FROM (1)

B = 90°-60° =30°

SO

tan(A+2B) tan(2A+B)

= tan (60°+ 60°) tan (120°+ 30°)

= tan 120° × tan 150°

= - cot 30° × tan 30°

= - 1

Hence the required answer is (b) - 1
