1. 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.
- 450
- 512
- 598
- 658
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}
2. 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?
- 300
- 400
- 500
- 600
Answer: Option C
Explanation:
N * 50 = (325000 - 300000) = 25000
N = 25000 / 50
= 500
3. Simplify
\begin{aligned}
16-[5-(6+2(7-\overline{8-5}))]
\end{aligned}
- 23
- 25
- 28
- 30
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}
4. 7500 + (1250 / 50)
- 7500
- 7525
- 7550
- 8000
Answer: Option B
Explanation:
As per BODMAS rule first we will solve the terms in the bracket then other.
= 7500 + (25) = 7525
