3. \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}

4. Evaluate
\begin{aligned}
\frac{3.6 \times 0.48 \times 2.50}{0.12 \times 0.09 \times 0.5}
\end{aligned}

80
800
8000
80000

Answer: Option B

Explanation:

\begin{aligned}
\frac{3.6 \times 0.48 \times 2.50}{0.12 \times 0.09 \times 0.5}
\end{aligned}

\begin{aligned}
= \frac{36 \times 48 \times 250}{12 \times 9 \times 5} = 800
\end{aligned}

5. 617 + 6.017 + 0.617 + 6.0017 = ?
