Question

9.03 divided by 899.8 is closest to?

a.0.01
b.0.001
c.1
d.100

Answer 1

answer : option (1) 0.01

explanation : This question is based on logic of approximation.

when a number is written as , x = a ± n

where a >> n , then, x ≈ a .

here, 9.03 = 9 + 0.3

it is clear that 9 >> 0.3

so, we can write , 9.03 ≈ 9

similarly, 899.8 = 900 - 0.2

here, 900 >> 0.2 so, 899.8 ≈ 900

now, 9.03 is divided by 899.8 means 9 is divided by 900.

i.e., 9.03/899.8 ≈ 9/900 ≈ 1/100 = 0.01

hence, option (1) is correct choice.

Answer 2

Answer : option (1) 0.01

now, 9.03 is divided by 899.8 means 9 is divided by 900.

i.e., 9.03/899.8 ≈ 9/900 ≈ 1/100 = 0.01

hence, option (1) is correct choice.
