Question : 16 of 100

Marks: +1, -0

16.003 x 29.998-40.002x 9.009=?

Solution:

Concept:

Use approximation to nearest whole numbers for quick calculation.

Explanation:

16.003 \approx 16

29.998 \approx 30

40.002 \approx 40

9.009 \approx 9

Now substitute:

16 \times 30 = 480

40 \times 9 = 360

480 - 360 = 120

The decimal parts are very small and nearly cancel out.

So the required value is closest to

120

Answer:

120

, which matches option C.
