Question Detail

Value of
$\begin{aligned} \frac{1}{2+\frac{1}{2+\frac{1}{2-\frac{1}{2}}}} \end{aligned}$

$\begin{aligned} \frac{6}{19} \end{aligned}$
$\begin{aligned} \frac{7}{19} \end{aligned}$
$\begin{aligned} \frac{8}{19} \end{aligned}$
$\begin{aligned} \frac{9}{19} \end{aligned}$

Answer: Option C

Explanation:

$\begin{aligned} = \frac{1}{2+\frac{1}{2+\frac{1}{\frac{3}{2}}}} \end{aligned}$
$\begin{aligned} = \frac{1}{2+\frac{1}{2+\frac{2}{3}}} \end{aligned}$

$\begin{aligned} = \frac{1}{2+\frac{1}{\frac{8}{3}}} \end{aligned}$

$\begin{aligned} = \frac{1}{2+\frac{3}{8}} \end{aligned}$

$\begin{aligned} = \frac{1}{\frac{19}{8}} \end{aligned}$

$\begin{aligned} = \frac{8}{19} \end{aligned}$

1. 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

2. Along a yard 225 metres long, 26 trees are palnted at equal distances, one tree being at each end of the yard. What is the distance between two consecutive trees

Answer: Option B

Explanation:

26 trees have 25 gaps between them,
Required distance (225/25) = 10

3. 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
= $\begin{aligned} \frac{28+14+7+4+2+1}{28} = \frac{56}{28} = 2\end{aligned}$

4. The number of girls in a class are 7 times the number of boys, which value can never be the of total students

Answer: Option D

Explanation:

Let the boys are X, then girls are 7X, total = X+7X = 8X

So it should be multiple of 8, 30 is not a multiple of 8.

5. Company workers decided to raise Rs. 3 lakhs by equal contribution from each. Had they contributed Rs. 50 each extra, the contribution would have been Rs. 3.25 lakhs. How many workers were they?

Answer: Option C

Explanation:

N * 50 = (325000 - 300000) = 25000
N = 25000 / 50
= 500
