Correct Answer: Rs. 2300

Solution : Let CP of the table be Rs. $y$
At a loss of 10%, Selling price = $\frac{(100-10)}{100}\times 2=\frac{90y}{100}$
According to the question,
$\frac{90y}{100}=1800$
⇒ $y=2000$
For a profit of 15%.
Selling Price = $\frac{2000 \times (10+15)}{100}=\text{Rs.}\ 2300$
Hence, the correct answer is Rs. 2300.

Correct Answer: Neither I nor II

Correct Answer: 300%

Solution : The area of a square = $s^2$, where $s$ is the length of a side.
If the side length is doubled, the new area = $(2s)^2 = 4s^2$
The increase in area = $4s^2 - s^2 = 3s^2$
The percentage increase in area $=\frac{3s^2}{s^2} \times

Correct Answer: Second from last

Correct Answer: 7

Solution : Given: $r\sin\theta=\frac{7}{2}$ ------(1)
$r\cos\theta=\frac{7\sqrt{3}}{2}$ ------(2)
Squaring and adding both equations, we have:
⇒ $r^{2}\sin^2\theta+r^{2}\cos^{2}\theta=(\frac{7}{2})^{2}+(\frac{7\sqrt{3}}{2})^{2}$
⇒ $r^{2}(\sin^2\theta+\cos^{2}\theta)=\frac{49}{4}+\frac{147}{4}$
⇒ $r^{2}=\frac{196}{4}$
⇒ $r^{2}=49$
$\therefore r=\sqrt{49}=7$
Hence, the correct answer is 7.

Correct Answer: $\frac{24}{7}$

Solution : Given: A can do 75% of a job in 9 days and B can do half of the job in 8 days.
Let the total work be $a$ units.
So, work done by A in 1 day = $\frac{75a}{100}×\frac{1}{9}$ = $\frac{a}{12}$ units,
and work done

Correct Answer: 24

Solution : For each figure, multiply and add the numbers in the top right and bottom left corners to get the top left and bottom right numbers respectively.
Figure one: 4 × 7 = 28; 4 + 7 = 11
Figure two: 5 × 5 = 25;

Correct Answer: 102

Solution : Given:
19, 9, 28, 37, 65, ?

Add the first two numbers to get the third number, then add the second and third numbers to get the fourth number, and so on.
19 + 9 = 28; 9 + 28 = 37; 28 + 37

Correct Answer: 27 – 53

Solution : Let's check the options –
First option: 18 – 37; (18 × 2) + 1 = 36 + 1 = 37
Second option: 33 – 67; (33 × 2) + 1 = 66 + 1 = 67
Third option: 29 – 59; (29
