Problem: a hostel had provisions for 250 men for 44 days . if 50 men left the hostel , how long will the food last at the same rate ?
Rationale: "a hostel had provisions for 250 men for 44 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 : 44 250 × 44 = 200 x 5 × 44 = 4 x x = 5 × 11 = 55 answer a"
annotated_formula: divide(multiply(250, 44), subtract(250, 50))
