Question Detail

Simplify
(31/10) * (3/10) + (7/5) / 20

Answer: Option B

Explanation:

= (31/10) * (3/10) + (7/5) / 20
= (3.1) * (.3) + (1.4) / 20
= 0.93 + 0.07
= 1

1. Simplify
$\begin{aligned} 16-[5-(6+2(7-\overline{8-5}))] \end{aligned}$

Answer: Option B

Explanation:

$\begin{aligned} = 16-[5-(6+2(7-8+5))] \end{aligned}$
(Please check due to overline, sign has been changed)

$\begin{aligned} = 16-[5-(6+2 \times 4))] \end{aligned}$

$\begin{aligned} = 16-[-9] = 16 + 9 = 25 \end{aligned}$

2. Simplify
$\begin{aligned} 1+\frac{1}{2}+\frac{1}{4}+\frac{1}{7}+\frac{1}{14}+\frac{1}{28} = ? \end{aligned}$

Answer: Option A

Explanation:

By taking LCM we get
=

$\begin{aligned} \frac{28+14+7+4+2+1}{28} = \frac{56}{28} = 2\end{aligned}$

3. (3080 + 6160) / 28

Answer: Option C

Explanation:

As per BODMAS rule, first we will solve the equation in bracket then we will go for division
= (9240)/28 = 330

4. Simplify
$\begin{aligned} 1\frac{3}{4}+5\frac{1}{3}+3\frac{2}{5} \end{aligned}$

$\begin{aligned}10\frac{29}{60} \end{aligned}$
$\begin{aligned}8\frac{29}{60} \end{aligned}$
$\begin{aligned}6\frac{29}{60} \end{aligned}$
$\begin{aligned}4\frac{29}{60} \end{aligned}$

Answer: Option A

Explanation:

$\begin{aligned} = \frac{7}{4}+\frac{16}{3}+\frac{17}{5} \end{aligned}$

$\begin{aligned} = \frac{105+320+204}{60} \end{aligned}$

$\begin{aligned} = \frac{629}{60} \end{aligned}$

$\begin{aligned} = 10\frac{29}{60} \end{aligned}$

5. 3034 - (1002 / 20.04) = ?
