At a certain point the angle of elevation of a tower is found to be such that its
P cotangent is \( 3 / 5 \); on walking \( 32 \mathrm{~m} \) directly towards the tower its angle of

W elevation is an angle whose cotangent is \( 2 / 3 \). Then the height of tower is
(B) \( 80 \mathrm{~m} \)
(A) \( 120 \mathrm{~m} \)
(C) \( 160 \mathrm{~m} \)
