Question : The population of a city increases compounded by 10% annually. The present population of this city is 1,33,100. What was the population of the city 2 years ago?
Option 1: 1,01,000
Option 2: 1,10,000
Option 3: 1,21,000
Option 4: 1,00,000
Correct Answer: 1,10,000
Solution : $P=P{_0}×(1+r)^t$ where: $P$ is the present population, $P{_0}$ is the past population, $r$ is the annual growth rate (as a decimal), and $t$ is the number of years. Given, $P{_0} = 133,100$ $r = 10\%$ We have to find the population 2 years ago ($t=−2$
Question : A can do in one day three times the work done by B in one day. They together finish $\frac{2}{5}$th of the work in 9 days. The number of days by which B can do the work alone is:

Option 3: 100 days
Option 4: 30 days
Correct Answer: 90 days
Solution : Given: A can do in one day three times the work done by B in one day. They together finish $\frac{2}{5}$th of the work in 9 days. Let the efficiency of B = $a$ units, So, the efficiency of A = 3$a$ units Here,

Question : Two cities P and Q are 181 km apart on a straight road. One man starts from P at 8:30 a.m. and travels toward Q at 30 km/hr. If another man starts from Q at 8:54 a.m. and travels towards P at a speed of 35 km/hr, then at what time will they meet?
Option 1: 11:30 a.m.
Option 2: 10:00 a.m.
Option 3: 10.30 a.m.
Option 4: 11:00 a.m.
Correct Answer: 11:30 a.m.
Solution : Distance between P and Q at 8:30 a.m. = 181 km Distance covered by P until Q starts = $30 \times \frac{24}{60}$ = 12 km Distance between P and Q at 8:54 a.m. = 181 − 12 = 169 km Let the time taken
Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. 12 : 100 :: 10 : 64 :: 14 : ?
Option 1: 140
Option 2: 144
Option 3: 124
Option 4: 134
Correct Answer: 144
Solution : Given: 12 : 100 :: 10 : 64 :: 14 : ?
Like, 12 : 100→(12 – 2)2 = 102 = 100 And, 10 : 64→(10 – 2)2 = 82 = 64 Similarly, follow the same pattern for 14 :
Question : If $5x-40=3x$, then the numerical value of $(2x-11)$ is:
Option 1: 29
Option 2: 39
Option 3: 19
Option 4: 9
Correct Answer: 29
Solution : Given: $5x-40=3x$ $⇒5x-3x=40$ $⇒2x=40$ $\therefore x=20$ Substituting the value of $x$ in $(2x-11)$, we get, $(2x-11)=2(20)-11=29$ Hence, the correct answer is 29.
