Pick: A) 35 B) 40 C) 50 D) 60 E) 65

Rationale: a hostel had provisions for 250 men for 28 days if 50 men leaves the hostel , remaining men = 250 - 50 = 200 we need to find out how long the food will last for these 200 men . let the required number of days = x days more men , less days ( indirect proportion ) ( men ) 250 : 200 : : x : 28 250 × 28 = 200 x 5 × 28 = 4 x x = 5 × 7 = 35 answer a
