Answer is (3) 1580
T1= m1(g+a1)
T2= m2(g)
T3= m3(g-a2)
Add all these tensions

For A
T1 = m (g + a)
= 60 (10 + 2)
= 720 N
For B
He is moving downwards with CONSTANT VELOCITY of 2 m/s
T2 = mg
= 50 × 10
= 500 N
For C
T3 = m (g - a)
= 40 × (10 - 1)
= 360 N
Tension in the rope = T1 + T2 + T3
= 720 N + 500 N + 360 N
= 1580 N
Correct option is (3)
