Gear 2 rotates at 1200 rpm is counter clockwise direction and engages with Gear 3 and Gear 4 mounted on the same shaft. Gear 5 engages with Gear 4. The numbers of teeth on Gears 2, 3, 4 and 5 are 20, 40, 15 and 30, respectively. The angular speed of Gear 5 is

1. 300 rpm counter clockwise
2. 300 rpm clockwise
3. 4800 rpm counter clockwise
4. 4800 rpm clockwise

Correct Option: A

N₅	=	T₂ × T₄	=	20 × 15
N₂	=	T₃ × T₅	=	40 × 30

⇒ N₅ = 1200 × 0.25 = 300 rpm ccw.
