Option 1: (1)

Question : If $a-b=2$ and $ab=24$, then what is the value of $a^3-b^3$?
Option 1: 280
Option 2: 124
Option 3: 140
Option 4: 152
Correct Answer: 152
Solution : Given: $a-b=2$ and $ab=24$ We know that $(a-b)^3=a^3-b^3-3ab(a-b)$ ⇒ $2^3=a^3-b^3-3(24)(2)$ ⇒ $a^3-b^3=8+3\times 24\times 2$ ⇒ $a^3-b^3=152$ Hence, the correct answer is 152.

Question : The population of the city was 12,50,000 in the year 2010. It increased at the rate of 2% per annum during the years 2011 and 2012. In the year 2013, it decreased by 1%. Find the population of the city at the end of 2013.
Option 1: 1,28,54,952
Option 2: 13,50,000
Option 3: 13,87,495
Option 4: 12,87,495
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.

Option 2: INR 28,250

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.
Question : Select the most appropriate option that can substitute the underlined words in the given sentence.
No sooner did we arrived at the airport than we got onto our flight to Atlanta.
Option 1: did we arrive at
Option 2: can we arrive by
Option 3: have we arrived at
Option 4: had we arrive at
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."
