Question Detail

\begin{aligned}
\frac{5 \times 1.6 - 2 \times 1.4}{1.3} = ?
\end{aligned}

Answer: Option D

Explanation:

As per given equation we can solve like this :

\begin{aligned}
= \frac{8 - 2.8}{1.3} \\
= \frac{5.2}{1.3} = \frac{52}{13} \\
= 4
\end{aligned}

1. Arrange the fractions in ascending order

5/8 < 7/12 < 3/4< 13/16
5/8 < 7/12 < 13/16 < 3/4
5/8 < 3/4< 13/16 < 7/12
7/12 < 5/8 < 3/4< 13/16

Answer: Option D

Explanation:

5/8 = .625, 7/12 = .5833, 3/4 = .75, 13/16 = .8125

So order will be
7/12 < 5/8 < 3/4< 13/16

2. Evaluate
\begin{aligned} \frac{10.3 \times 10.3 \times 10.3 + 1}{10.3 \times 10.3 - 10.3 + 1}
\end{aligned}

113
1.13
11.3
113

Answer: Option C

Explanation:

\begin{aligned}
a^3 + b^3 = (a+b)(a^2 + b^2 - ab)
\end{aligned}

\begin{aligned}
= \frac{10.3^3 + 1^3}
{10.3^2 + 1^2 - 10.3 \times 1}
\end{aligned}

\begin{aligned}
= (a+b) = (10.3+1) = 11.3
\end{aligned}
