Question Detail

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
=

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

1. What fraction of $\begin{aligned} \frac{4}{7}\end{aligned}$ should be added to itself to become $\begin{aligned} 1\frac{1}{14} \end{aligned}$

$\begin{aligned} \frac{7}{8} \end{aligned}$
$\begin{aligned} \frac{7}{9} \end{aligned}$
$\begin{aligned} \frac{7}{10} \end{aligned}$
$\begin{aligned} \frac{7}{11} \end{aligned}$

Answer: Option A

Explanation:

$\begin{aligned} => \frac{4}{7}x + \frac{4}{7} = \frac{15}{4} \end{aligned}$

$\begin{aligned} = \frac{4}{7}x = \frac{15}{4} - \frac{4}{7} \end{aligned}$

$\begin{aligned} = \frac{4}{7}x = \frac{7}{14} \end{aligned}$

$\begin{aligned} = x = \frac{1}{2}\times \frac{7}{4} = \frac{7}{8} \end{aligned}$

2. 3640 ÷ 14*16 + 340 = ?

3500
4500
1500
2500

Answer: Option B

3. In a class free notebooks were distributed among all the children. Each child got notebooks which were one-eighth of the number of children. If number of children been half, then each child would have recieved 16 notebooks in total. Find the total number of books distributed.

Answer: Option B

Explanation:

Let suppose total number of students in class are X.
Then from the question we can conclude it that,

$\begin{aligned} X*\frac{1}{8}X = \frac{X}{2}*16 \\ => X = 64\\ \text{Total notebooks,} \\ = \frac{1}{8}X^2 \\ = \left( \frac{1}{8} * 64 * 64 \right) \\ = 512 \end{aligned}$

4. Value of $\begin{aligned} 2^5 \times 9^2 \end{aligned}$ has been written as 2596, what is the difference between actual value.

Answer: Option D

5. 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:

=

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