Question
What is the minimum number of square marbles required to
tile a floor of length 2 metres 8cm and width 2 metres 86 cm? ÂSolution
If there is a requirement of minimum number of tiles , we must take the maximum size of the side. The side of square tile required to tile a floor of length 208cm & 286cm =HCF (208,286) = 26cm . So area of 1 square tile = 26cm ×26cm & Area of the floor = 208cm×286cm.                                 So number of tiles = Area of floor/ area of 1 tile = (208cm×286cm)/(26cm ×26cm) = 8 ×11 =88.

2380.03 ÷ 84.98 x 39.9 = ? + 15.32
15.232 + 39.98% of 539.99 = ? × 6.99
(100.01% of 44.89) ÷ 14.98 = √? - √48.98
20.22 × 11.99 + 140.15 = ?
What approximate value should replace the question mark?
12.45% of 640.20 − 60% of 2500 = ? − 9000.10
