Question : A boat goes a certain distance at 30 km/hr and comes back the same distance at 60 km/hr. What is the average speed (in km/hr) for the total journey?
Option 1: 45 km/hr
Option 2: 50 km/hr
Option 3: 40 km/hr
Option 4: 35 km/hr
Correct Answer: 40 km/hr
Solution : Given: The speed of the boat is 30 km/hr and 60 km/hr for the same distance. So, average speed = $\frac{2xy}{x+y}$, where $x$ and $y$ are two given speeds of the boat (for the same distance). Putting the values $x$ = 30 and $y$
Question : If $x+y+z = 22$ and $xy+yz+zx = 35$, then what is the value of $\small (x-y)^{2}+(y-z)^{2}+(z-x)^{2}$?
Option 1: 793
Option 2: 681
Option 3: 758
Option 4: 715
Correct Answer: 758
Solution : Given: $x+y+z = 22$ and $xy+yz+zx = 35$ We know that $(x+y+z)^2 = x^2+y^2+z^2+2(xy+yz+zx)$ ⇒ $22^2 = x^2+y^2+z^2+2\times 35$ ⇒ $484 = x^2+y^2+z^2+70$ ⇒ $x^2+y^2+z^2 = 484-70 = 414$ So, $(x-y)^2+(y-z)^2+(z-x)^2 = 2[x^2+y^2+z^2-(xy+yz+zx)]$ ⇒ $(x-y)^2+(y-z)^2+(z-x)^2 = 2[414-35]$ $\therefore(x-y)^2+(y-z)^2+(z-x)^2 = 758$ Hence, the correct answer is
Question : Direction: In the following question, a statement is given followed by two conclusions / Assumptions. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follow from the given statement.
Statement
If people are intelligent they should be creative.
Assumptions
I. Creativity and intelligence are related.
II. Creative people are intelligent.
Option 1: Both assumptions I and II are invalid
Option 2: Only assumption I is valid
Option 3: Only assumption II is valid
Option 4: Both assumptions I and II are valid
Correct Answer: Only assumption I is valid
Solution : Given:
If people are intelligent, they should be creative.
Now, let's assess the assumptions:
I. Creativity and intelligence are related. This assumption is supported by the statement. The statement implies that there is a relationship between intelligence and creativity. It
Question : If two successive discounts of 20% and 30% are given, what is the net discount (in %)?
Option 1: 40
Option 2: 44
Option 3: 56
Option 4: 60
Correct Answer: 44
Solution : Single equivalent discount = $(a+b-\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts. So, the single discount of two successive discounts of 20% and 30% $=20+30-\frac{20×30}{100}=44\%$ Hence, the correct answer is 44.
Question : Study the given graph and answer the question that follows. The total production of computers in 2013, 2015, and 2018 is x% of the total exports of computers by the company during the six years. The value of x is:
Option 1: $46 \frac{1}{3}$
Option 2: $52 \frac{1}{3}$
Option 3: $53 \frac{1}{3}$
Option 4: $49 \frac{2}{3}$
Correct Answer: $53 \frac{1}{3}$
Solution : Production of computers in 2013 = 180, in 2015 = 300, in 2018 = 320 Exports of computers in 2013 = 140, in 2014 = 240, in 2015 = 200, in 2016= 350, in 2017 = 300, in 2018 = 270 Calculation: The production
