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. 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}

2. Evaluate
\begin{aligned}
\frac{2.39^2 - 1.61^2}{2.39 - 1.61}
\end{aligned}

Answer: Option C

Explanation:

Use following formula to solve it quickly
\begin{aligned}
\frac{a^2-b^2}{a-b}=\frac{(a+b)(a-b)}{(a-b)} = (a+b)
\end{aligned}
= (2.39+1.61) = 4
