Aptitude - Simplification Problem Solved
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
