What will come in the place of ? in the following question?

(88.128 / ? ) / {(2.4 x 0.3)/(0.2 x 1.5)} = 18

a)1.04
b)2.04
c)3.04
d)4.04

Answer : b)2.04

Solution:

Given that (88.128 / ? ) / {(2.4 x 0.3)/(0.2 x 1.5)} = 18

Let us take ? as X.

Then, (88.128/X)/{(0.72) / (0.3)} = 18

(88.128/X)/2.4 = 18

88.128/X = 18 x 2.4

88.128/X = 43.2

43.2 x X = 88.128

X = 88.128 / 43.2

X = 2.04

Hence the answer will be 2.04
