A rectangular carpet 2.5m long and 2.4m wide covers 5% of a rectangular floor. Calculate the area of the floor
A
30m2
B
57m2
C
120m2
D
225m2
correct option: c

Area of carpet = 2.5 x 2.4 = 6

Let F represent the floor

6 = 5% of F

6 = (\frac{5}{100}) x F

5F = 6 x 100

F = 6 x (\frac{100}{5})

= 120m2
