Aptitude Question ID : 93926

Which of the following is greatest :
0.7 + \sqrt{0.16}, 1.02 - \frac{0.6}{24}, 1.2\times 0.83 and \sqrt{1.44}
[A]1.02 - \frac{0.6}{24}
[B]0.7 + \sqrt{0.16}
[C]\sqrt{1.44}
[D]1.2\times 0.83

\mathbf{\sqrt{1.44}}
\because 0.7 + \sqrt{0.16} = 0.7+0.4 = 1.1
and 1.02 - \frac{0.6}{24} = 1.02 - 0.025 = 0.995
and 1.2 \times 0.83 = 0.996
and \sqrt{1.44} = 1.2
Hence the greatest number =\sqrt{1.44}.
