Ram wants to paint all the walls and ceiling of his reading room personally. He started painting his room and after painting the area of 16 m2, a paint tin of 4 litres is exhausted. How many paint tins are required to paint the remaining area, if the total area of his room to be painted is 176 m2?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 10.
Total area of the room = 176 m2
Area covered = 176 - 16 = 160 m2
4 liters = 16 m2
1 liter = 4 m2 or 1 m2 = 1/4 liter
Remaining area = 160 m2
160 m2 = 160/4 = 40
Capacity of 1 tin = 4 liters
then, number of tins required to paint the remaining area = 40/4 = 10 tins
