One coolie takes 1 minute to raise a suitcase through a height of 2 m but the second coolie takes 30 s to raise the same suitcase to the same height. The powers of two coolies are in the ratio of

1. 1 : 2
2. 1 : 3
3. 2 : 1
4. 3 : 1

Correct Option: A

∵ Power P =	w
	t

⇒	P₁	=	t₂	=	30 s	=	30 s	=	1
	P₂		t₁		1 minute		60 s		2

(t₁ = 1 minute; t₂ = 30 second given)
