Answer: Option A

Explanation:

Let the original price per egg be Rs x
Then increased price will be,
$$\begin{aligned} \left(\frac{130}{100}x\right) \\ => \frac{7.80}{x}-\frac{7.80}{\frac{130}{100}x} = 3\\ => \frac{7.80}{x}-\frac{780}{130x} = 3 \\ => 390x = 234 \\ => x = 0.6 \\ \text{Actual price was Rs 0.6} \\ \text{Present price per dozen will be} \\ Rs.\left(12*\frac{130}{100}*0.6 \right) \\ = Rs. 9.36 \end{aligned}$$

Answer: Option C

Explanation:

It is , y% of z = 2(x% of y)
=> yz/100 = 2xy/100
=> z = 2x

Answer: Option B

Explanation:

Question of this type looks a bit typical, but it is too simple, as below...

It will be 8 * 20/100 = 1.6

Answer: Option B

Explanation:

Let the total number is x,
then,

(100-25)% of (100 - 10)% x = 4050
=> 75% of 90% of x = 4050
=> 75/100 * 90/100 * x = 4050
=> x = (4050*50)/27 = 6000

Answer: Option A

Explanation:

Actual Price = Rs.25 + Rs.2.50 = Rs.27.5

Saving = Rs.2.5

$$\begin{aligned}\text{Percentage Saving = }\dfrac{2.5}{27.5}\times 100 \\ = \dfrac{250}{27.5} = \dfrac{2500}{275}\\ = \dfrac{100}{11} = 9\dfrac{1}{11}\% \approx 9\%\end{aligned}$$
