Question Detail

3640 ÷ 14*16 + 340 = ?

3500
4500
1500
2500

Answer: Option B

1. (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

2. 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,

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

3. 5004 / 139 - 6

Answer: Option D

4. If p - q = 3 and
$\begin{aligned} p^2 + q^2 = 29 \end{aligned}$ , find the value of pq.

Answer: Option D

Explanation:

We know

$\begin{aligned} 2ab = (a^2 + b^2) - (a - b)^2 \end{aligned}$

$\begin{aligned} 2pq = 29 - 9 = 20 \end{aligned}$

$\begin{aligned} =>pq = 10 \end{aligned}$

5. 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
