Question Detail

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

1. 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}

2. Which is in ascending order

3/2, 9/11, 7/9, 8/9
3/2, 7/9, 9/11, 8/9
9/11, 8/9, 3/2, 7/9
7/9, 3/2, 9/11, 8/9

Answer: Option B

3. Which is in descending order

11/17, 7/11, 8/15, 5/9
11/17, 5/9, 7/11, 8/15
5/9, 8/15, 11/17, 7/11
11/17, 7/11, 5/9, 8/15

Answer: Option D

4. 34.95 + 240.016 + 23.98 = ?

288.946
298.946
198.946
188.946

Answer: Option B

5. 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}
