Question : Directions: In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which conclusions logically follow the given statements. Statements: I. All B is V. II. All K is B. Conclusions: I. All K is V. II. No V is B.
Option 1: Both conclusions I and II follow
Option 2: Neither conclusion follows
Option 3: Only conclusion I follows
Option 4: Only conclusion II follows
Correct Answer: Only conclusion I follows
Solution : The possible Venn diagram according to the given statement is as follows –
Let's analyse the conclusions – Conclusion I: All K is V – From the Venn diagram, it is evident that the circle representing K is completely overlapped by the
Question : The ratio of the curved surface area of two cones is 1 : 4 and the ratio of slant height of the two cones is 2 : 1. What is the ratio of the radius of the two cones?
Option 1: 1 : 2
Option 2: 1 : 4
Option 3: 1 : 8
Option 4: 1 : 1
Correct Answer: 1 : 8
Solution : The curved surface area of a cone $ = \pi rl$ where \(r\) is the radius and \(l\) is the slant height of the cone. Given that the ratio of the curved surface areas of two cones = 1 : 4 $⇒\frac{\pi r_1
Question : If $\tanθ + \cotθ = 2$, $\theta$ is an acute angle, then find the value of $2 \tan^{25}θ + 3 \cot^{20}θ + 5 \tan^{30}θ \cot^{15}θ$.
Option 1: 8
Option 2: 6
Option 3: 10
Option 4: 12
Correct Answer: 10
Solution : Given: The value of the trigonometric equation is $\tanθ + \cotθ = 2$ where $θ$ is an acute angle. $\tanθ + \cotθ = 2$ ⇒ $\tan 45^{\circ} + \cot45^{\circ} = 2$ ⇒ $\theta = 45^{\circ}$ The value of the trigonometric expression $2 \tan^{25}45^{\circ} + 3
Question : Directions: Which of the following numbers will replace the question mark (?) and complete the given number series? 2, 12, 144, 2592, ?
Option 1: 62108
Option 2: 62208
Option 3: 62204
Option 4: 63408
Correct Answer: 62208
Solution : Given: 2, 12, 144, 2592, ?
The pattern is as follows –
So, 62208 is the missing number of the series. Hence, the second option is correct.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (4, 9, 16) (25, 36, 49)
Option 1: (49, 64, 81)
Option 2: (1, 16, 49)
Option 3: (36, 81, 49)
Option 4: (49, 36, 81)
Correct Answer: (49, 64, 81)
Solution : Given: (4, 9, 16); (25, 36, 49)
The given numbers are squares of consecutive natural numbers – ⇒ (4, 9, 16)→22 = 4; (2 + 1)2 = 32 = 9; (3 + 1)2 = 42 = 16 ⇒
