Correct Answer: 12,87,495

Solution : The population of the city in 2010 is 1250000.
Then, Population, $P$ = 1250000
Rate of increment, $R$ = 2%
We have to find the population at the end of the year 2012, i.e. time, $n$ = 2 years
Population after 2 years is given by
New Population $= P(1+\frac{R}{100})^n$
$=1250000(1+\frac{2}{100})^2$
$=1250000\times \frac{51}{50}\times \frac{51}{50}$
$=13,00,500$
Again it decreased by 1%
$R = –1$%
New Population $= P(1-\frac{R}{100})$
$=1300500(1-\frac{1}{100})$
$=1300500\times \frac{99}{100}$
$=12,87,495$
Hence, the correct answer is 12,87,495.

According to the given information, the family tree will be as follows –

Here, the quadrilateral represents the male, and the circular figure represents the female in the figure.

From the above family tree, Z is the daughter of V. Hence, the fourth option is correct.

Correct Answer: pell-mell

Correct Answer: INR 27,250

Solution : Given: The Rate of Simple Interest in consecutive years is 4% and 5% respectively.
Principal = INR 25,000
Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$
Putting the values, we have,
Simple interest = $\frac{25000×4×1}{100}+\frac{25000×5×1}{100}$
= 1000 + 1250
= 2250
Total amount = 25000 + 2250 = 27250
Hence, the correct answer is INR 27,250.

Correct Answer: did we arrive at

Solution : The first option is the correct answer.

"No sooner did we arrive at" follows the correct inversion of the subject and auxiliary verb after the phrase, "no sooner". In English, when no sooner is used to indicate an action that happens immediately after another, the auxiliary verb and subject are inverted. So, did we arrived at should be replaced with "did we arrive at" as did is followed by the first form of the verb making the sentence grammatically correct.

Therefore, the correct sentence is: "No sooner did we arrive at the airport than we got onto our flight to Atlanta."
