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}

1. 0.7683 + 0.369 + 0.05 + 0.8 = ?

1.9873
0.9873
1.8873
1.9872

Answer: Option A

2. 617 + 6.017 + 0.617 + 6.0017 = ?

62.96357
62963.57
62.96357
629.6357

Answer: Option D

3. 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}

4. Value of
\begin{aligned}
0.5\overline{6}
\end{aligned}

\begin{aligned} \frac{51}{99} \end{aligned}
\begin{aligned} \frac{51}{90} \end{aligned}
\begin{aligned} \frac{51}{9} \end{aligned}
\begin{aligned} \frac{510}{99} \end{aligned}

Answer: Option B

Explanation:

\begin{aligned}
0.5\overline{6} = \frac {56 - 5}{90} = \frac {51}{90}
\end{aligned}

5. Arrange fractions in descending order

9/11 > 8/9 > 3/5 > 4/7
9/11 > 8/9 > 4/7 > 3/5
8/9 > 9/11 > 3/5 > 4/7
9/11 >3/5 > 8/9 > 4/7

Answer: Option C

Explanation:

9/11 = .818 , 8/9 = .88 , 3/5 = .6, 4/7 = .571

So order is 8/9 > 9/11 > 3/5 > 4/7
