Option 1: L12H
Option 2: L12G
Option 3: L14G
Option 4: L13G
Correct Answer: L12G
Solution : Given: E25I : A5E :: Z49T : V7P :: P144K : ?
Like, E25I : A5E→E(5) – 4 = A; √25 = 5; I(9) – 4 = E And, Z49T : V7P→Z(26) – 4 = V; √49 = 7; T(20) – 4 = P Similarly,
Question : Study the pie-chart carefully and answer the questions. What is the central angle corresponding to the total expenditure, expenditure on education in the given figure?
Option 1: 55.8°
Option 2: 55.2°
Option 3: 52°
Option 4: 42°
Correct Answer: 55.8°
Solution : From the given figure, Total = 5250 + 6125 + 7525 + 6475 + 4200 + 5425 = 35000 For education, amount spent = 5425 Central angle = $\frac{\text{Amount spent on education}}{\text{Total amount spent}}\times360°$ = $\frac{5425}{35000}\times 360°$ = 55.8° Hence, the correct answer is 55.8°.
Question : The sum of the two numbers is 1224 and their HCF is 68. The number of pairs of numbers satisfying the above condition is:
Option 1: 3
Option 2: 4
Option 3: 6
Option 4: 2
Correct Answer: 3
Solution : Given: The sum of the two numbers is 1224 and their HCF is 68. Let the two numbers be $68x$ and $68y$. According to the question, $68x + 68y=1224$ ⇒ $x+y=18$ So, the possible pairs of values which are co-prime to each other are (1,
Question : The number of hours spent by a student on different activities as shown in the following pie chart: The central angle corresponding to the sleeping time is what percentage of the whole central angle?
Option 1: 66.66%
Option 2: 33.33%
Option 3: 55%
Option 4: 50%
Correct Answer: 33.33%
Solution : Number of hours spent on sleeping = 8 Total hours spent in all activities = 24 Required percentage = $\frac{\text{Time spent on sleeping}}{\text{Total hours in all activities}}\times100$ = $\frac{8}{24}\times100$ = 33.33% Hence, the correct answer is 33.33%.

Question : The population of a town increases each year by 4% of its total at the beginning of the year. If the population on 1st January 2001 was 500000, what was it on 1st January 2004?
Option 1: 562432
Option 2: 652432
Option 3: 465223
Option 4: 564232
Correct Answer: 562432
Solution : The population after $n$ years can be calculated by using the formula $P(1+\frac{\text{R}}{100})^n$ where $P$ is the initial value, $R$ is the rate and $n$ is the time. The population on 1st January 2001 was 500000. Population after 3 years $= 500000(1+\frac{4}{100})^3$ $= 500000(1+\frac{1}{25})^3$
Question : The speed of a boat in still water is 15 km/hr, and the speed of the current is 5 km/hr. In how much time (in hours) will the boat travel a distance of 60 km upstream and the same distance downstream?
Option 1: 20
Option 2: 12
Option 3: 9
Option 4: 10
Correct Answer: 9
Solution :
Given, The speed of a boat in still water is 15 km/hr The speed of the current is 5 km/hr Distance of upstream or downstream = 60 km We know, $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$ Also, If the speed of the boat is $x$ km/hr, and the
Question : Directions: In the following question, select the related number from the given alternatives. 3222 : 7222 :: 3323 : ?
Option 1: 9949
Option 2: 8838
Option 3: 7727
Option 4: 2212
Correct Answer: 7727
