Question : Directions: Read the given statements and conclusions carefully. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. You have to decide which conclusion/s logically follow/s from the given statements. Statements: Some chips are potatoes. All potatoes are fries. All fries are snacks. Conclusions: (I) All potatoes are snacks. (II) Some snacks are chips.
Option 1: Both conclusions (I) and (II) do not follow
Option 2: Only conclusion (I) follows
Option 3: Both conclusions (I) and (II) follow
Option 4: Only conclusion (II) follows
Correct Answer: Both conclusions (I) and (II) follow
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion I: All potatoes are snacks – From the above diagram, it is clear that there is a direct relation between potatoes
Question : ABC is an isosceles right-angle triangle. $\angle ABC = 90 ^{\circ}$ and AB = 12 cm. What is the ratio of the radius of the circle inscribed in it to the radius of the circle circumscribing $\triangle ABC$?
Option 1: $6–\sqrt{2}: 3 \sqrt{2}$
Option 2: $2–\sqrt{2}: \sqrt{2}$
Option 3: $6–3 \sqrt{2}: 1 \sqrt{2}$
Option 4: $6–3 \sqrt{2}: 6 \sqrt{2}$
Correct Answer: $2–\sqrt{2}: \sqrt{2}$
Solution : Given: ABC is an isosceles right-angle triangle. $\angle ABC = 90 ^{\circ}$ and AB = 12 cm. In $\triangle ABC$, $H^2=B^2+P^2$ (Using Pythagoras theorem). ⇒ $H^2=12^2+12^2$ ⇒ $H^2=144+144=288$ ⇒ $H=\sqrt{288}=12\sqrt2$ cm Inradius of inscribed circle of right angled triangle = $\frac{(P + B –
Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it. (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.) (2, 2, 4); (1, 6, 6); (7, 2, ?)
Option 1: 14
Option 2: 2
Option 3: 7
Option 4: 12
Correct Answer: 14
Solution : Given: (2, 2, 4); (1, 6, 6); (7, 2, ?)
Like, (2, 2, 4)→2 × 2 = 4 (1, 6, 6)→1 × 6 = 6 Similarly, (7, 2, ?)→7 × 2 = 14
So, 14 is the required answer. Hence, the first option is correct.
Question : What is the value of $\frac{7}{2}+\frac{11}{3}+\frac{7}{6}+\frac{11}{15}+\frac{7}{12}+\frac{11}{35}+\ldots \ldots+\frac{7}{156}+\frac{11}{575}$?
Option 1: $\frac{3917}{355}$
Option 2: $\frac{3816}{325}$
Option 3: $\frac{3714}{345}$
Option 4: $\frac{3216}{315}$
Correct Answer: $\frac{3816}{325}$
Solution : Given: The series is $\frac{7}{2}+\frac{11}{3}+\frac{7}{6}+\frac{11}{15}+\frac{7}{12}+\frac{11}{35}+\ldots \ldots+\frac{7}{156}+\frac{11}{575}$. Determine the value of the series by solving two distinct series independently. The sum of the first series = $\frac{7}{2}+\frac{7}{6}+\frac{7}{12}+...+\frac{7}{156}$ ⇒ Sum = $7[1–(\frac{1}{2})+(\frac{1}{2}–\frac{1}{3})+(\frac{1}{3}–\frac{1}{4})+...+(\frac{1}{12}–\frac{1}{13})]$ ⇒ Sum = $7[1–\frac{1}{13}]$ ⇒ Sum = $7\times\frac{12}{13}=\frac{84}{13}$ The sum of the second series =
Question : Directions: Select the correct combination of mathematical signs to replace × signs and to balance the following equation. 5 × 9 × 3 × 6 × 8
Option 1: ×, +, =, ×
Option 2: ×, –, =, ×
Option 3: +, ÷, –, =
Option 4: +, ×, ÷, =
Correct Answer: ×, +, =, ×
Solution : Given: 5 × 9 × 3 × 6 × 8
On replacing × with the mathematical signs – First option: ×, +, =, × L.H.S. = 5 × 9 + 3 = 45 + 3 = 48 R.H.S. = 6 × 8
Question : Directions: Select the option related to the third term in the same way as the second term is related to the first term. MONDAY : RJSIVD :: TROUBLE : ?
Option 1: XWJPFQJ
Option 2: YVJPFQZ
Option 3: YWJPGQZ
Option 4: CWJQGQZ
Correct Answer: YWJPGQZ
Solution : Given: MONDAY : RJSIVD :: TROUBLE : ?
Add 5 to the consonants and subtract 5 from the vowels of the given term to obtain the required term – M + 5 = R; O – 5 = J; N + 5 = S; D
Question : If $x+\left [\frac{1}{(x+7)}\right]=0$, what is the value of $x-\left [\frac{1}{(x+7)}\right]$?
Option 1: $3\sqrt{5}$
Option 2: $3\sqrt{5}-7$
Option 3: $3\sqrt{5}+7$
Option 4: $8$
Correct Answer: $3\sqrt{5}-7$
Solution : Given: $x+[\frac{1}{(x+7)}]=0$ Adding both sides 7, we get, ⇒ $x+7+[\frac{1}{(x+7)}]=7$ Squaring both sides, we get, ⇒ $(x+7)^{2}+(\frac{1}{x+7})^{2}+2=49$ ⇒ $(x+7)^{2}+(\frac{1}{x+7})^{2}=47$ Subtracting 2 from both sides, $(x+7)^{2}+(\frac{1}{x+7})^{2}–2=47-2$ ⇒ $[(x+7)-(\frac{1}{x+7})]^{2}=45$ ⇒ $[(x+7)-(\frac{1}{x+7})]=\sqrt{45}$ ⇒ $[(x-\frac{1}{x+7})]=\sqrt{45}-7=\sqrt{9 \times5}-7=3\sqrt{5}–7$ Hence, the correct answer is $3\sqrt{5}-7$.
Question : Directions: The position of how many letters will remain unchanged if each letter in the word KINGDOM is arranged alphabetically.
Option 1: Three
Option 2: None
Option 3: One
Option 4: Two
Correct Answer: None
Solution : Given: KINGDOM When the letters of KINGDOM are arranged in alphabetical order, the letter cluster formed is DGIKMNO. Now, the position of the letters that remain unchanged in the new letter cluster formed is as follows –
So, from the above figure, it can be
Question : Directions: In the following question, some parts of the sentence may have some errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No error".
The boy who studies hard (1) / he will pass (2) / with flying colours. (3) / No error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (2)
Solution : The error lies in the second part of the sentence.
The pronoun he should be removed as its use is superfluous and makes the sentence incoherent. The clause will pass with flying colours needs to be linked with the preceding clause, and the removal of
Question : Parts of the following sentence have been given as options. Select the option that contains an error.
You need to acknowledge the itinary and accommodation details of your journey as per the given calendar.
Option 1: calendar
Option 2: accommodation
Option 3: acknowledge
Option 4: itinary
Correct Answer: itinary
Solution : The correct choice is the fourth option.
The error lies in the misspelling of "itinerary". The correct spelling is itinerary. An itinerary refers to a planned route or travel schedule, and the correct spelling is crucial for clarity and accuracy in communication.
Therefore, the correct
