Aptitude Question ID : 93926
Which of the following is greatest :
$latex 0.7 + \sqrt{0.16},$ $latex 1.02 – \frac{0.6}{24},&s=1$ $latex 1.2\times 0.83&s=1$ and $latex \sqrt{1.44}$
[A]$latex 1.02 – \frac{0.6}{24}&s=1$
[B]$latex 0.7 + \sqrt{0.16}$
[C]$latex \sqrt{1.44}$
[D]$latex 1.2\times 0.83$
$latex \mathbf{\sqrt{1.44}}$
$latex \because 0.7 + \sqrt{0.16} = 0.7+0.4 = 1.1$
and $latex 1.02 – \frac{0.6}{24} = 1.02 – 0.025 = 0.995$
and $latex 1.2 \times 0.83 = 0.996$
and $latex \sqrt{1.44} = 1.2$
Hence the greatest number $latex =\sqrt{1.44}$.
