Question
One carton can hold 85 soap bars. Shally wants to pack 338 soap bars. How many cartons does she need for packing all of them?
Solution
Number of soap bars that can be packed in 1 carton = 85
Number of soap bars that can be packed in 2 cartons = 2 × 85 = 170
Number of soap bars that can be packed in 3 cartons = 3 × 85 = 255
Number of soap bars that can be packed in 4 cartons = 4 × 85 = 340
If we take 3 cartons, then we can pack only 255 soap bars.
Thus, Shally will need 4 cartons to pack 338 soap bars.
