Question : In a triangle PQR, $\angle$Q = 90°. If PQ = 12 cm and QR = 5 cm, then what is the radius (in cm) of the circumcircle of the triangle?
Option 1: $5$
Option 2: $6$
Option 3: $6.5$
Option 4: $6\sqrt2$
Correct Answer: $6.5$
Solution : Given: In a triangle PQR, $\angle$Q=90°, PQ = 12 cm, and QR = 5 cm. Let the hypotenuse of the triangle be $h$ cm. So, $h^2=12^2+5^2$ ⇒ $h=\sqrt{169}$ ⇒ $h=13$ cm We know, The circumradius of a right-angled triangle is half of its hypotenuse. So,
Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: I. Some pens are books. II. All books are compasses. III. Some compasses are pins. Conclusions: I. Some compasses are pens. II. All compasses are pens. III. Some pins are books. IV. Some compasses are books.
Option 1: Only conclusions I and II follow
Option 2: Only conclusions I and III follow
Option 3: Only conclusions I and IV follow
Option 4: Only conclusions III and IV follow
Correct Answer: Only conclusions I and IV follow
Solution : The possible Venn diagram, according to the given statements is as follows –
Let's analyse the conclusions – Conclusion I: Some compasses are pens – From the Venn diagram, we can see that the two circles representing compasses and pens

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."
College girls seldom wear (1) / sarees these days, (2) / do they? (3) / No error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (4)
Solution : The error lies in the third part of the sentence.

Question : The following table shows the production of different types of two-wheelers from 1993 to 1998. Number of two-wheelers (in 1000s)
In which year is the percentage increase in the total production minimum in comparison to the previous year?
Option 1: 1994
Option 2: 1995
Option 3: 1996
Option 4: 1997
Correct Answer: 1995
Solution : Percentage increase in total production in 1994 in comparison to the previous year = $\frac{237-215}{215}×100$ = 10.23% Percentage increase in total production in 1995 in comparison to the previous year = $\frac{251.5-237}{237}×100$ = 6.12% Percentage increase in total production in 1996 in comparison to the
Question : The smallest fraction which should be added to the sum of $2\frac{1}{2}, 3\frac{1}{3}, 4\frac{1}{4}$ and $5\frac{1}{5}$ to make the result a whole number is:
Option 1: $\frac{13}{60}$
Option 2: $\frac{1}{4}$
Option 3: $\frac{17}{60}$
Option 4: $\frac{43}{60}$
Correct Answer: $\frac{43}{60}$
Solution : Given: $2\frac{1}{2} +3\frac{1}{3} + 4\frac{1}{4} +5\frac{1}{5}$ To make this expression a whole number, add fractions: $ = (\frac{1}{2} +\frac{1}{3} + \frac{1}{4} +\frac{1}{5})$ $ = \frac{(30+20+15+12)}{60}$ $ = \frac{77}{60}$ $ = 1 +\frac{17}{60}$ The smallest fraction to be added = $1 -\frac{17}{60} =\frac{43}{60}$ Hence, the correct
Question : Directions: A series is given below with one term missing. Choose the correct alternative from the given ones that will complete the series. $\frac{W}{S}$, $\frac{U}{O}$, $\frac{S}{K}$, $\frac{Q}{G}$, ?
Option 1: $\frac{P}{R}$
Option 2: $\frac{C}{O}$
Option 3: $\frac{R}{J}$
Option 4: $\frac{O}{C}$
Correct Answer: $\frac{O}{C}$
Solution : Given: $\frac{W}{S}$, $\frac{U}{O}$, $\frac{S}{K}$, $\frac{Q}{G}$, ?
In the given series, subtract 2 from the place value of the letter in the numerator and subtract 4 from the place value of the letter in the denominator to obtain the missing term – $\frac{W\text{ – }2}{S\text{ –
Question : Directions: Select the option figure in which the given figure is embedded (rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation of the figure is not allowed, so we will check where the question figure can exactly fit itself in the given option figures.
From the above, it is clear that the given question figure is embedded in the third option figure. Hence, the
