a hostel had provisions for 250 men for 48 days . if 50 men left the hostel , how long will the food last at the same rate ?
"a hostel had provisions for 250 men for 48 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 : 48 250 × 48 = 200 x 5 × 48 = 4 x x = 5 × 12 = 60 answer d"
divide(multiply(250, 48), subtract(250, 50))
