Correct Answer: Only conclusion II follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some Legos are puzzles – From the Venn diagram, it is evident that there is no direct relation between Legos and puzzles.
Question : During a school excursion, each student of the junior school was charged Rs. 325 and each student of the senior school was charged Rs. 400. If there were 80 students from junior school and the combined average amount charged per student was Rs. 352, how many students from senior school went for the excursion?
Option 1: 55
Option 2: 45
Option 3: 50
Option 4: 40
Correct Answer: 45
Solution : Let the number of seniors be $x$. The total amount of money charged from the juniors $=325 \times 80= 26000$ Total amount of money charged from all students $= 352 \times (80 + x)$ The total amount charged from the seniors $ =400 \times x$

Question : A person standing at a distance looks at a building having a height of 1000 metres. The angle between the top of the building and the ground is 30o. At what approximate distance (in metres) is the person standing away from the building?
Option 1: 1000
Option 2: 936
Option 3: 1732
Option 4: 1542
Correct Answer: 1732
Solution : Given: AB = Height of the building = 1000 metres Let the distance of the man from the building, BC be $x$. From $\triangle$ ABC, we get $\tan 30° = \frac{AB}{BC}$ ⇒ $\frac{1}{\sqrt{3}}= \frac{1000}{x}$ ⇒ $ x = 1000\sqrt{3}$ ⇒ $x$ = 1000 × 1.732
Question : Direction: Given equations are solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.
2 + 4 + 6 = 48 and 3 + 2 + 8 = 48 , then 2 + 5 + 7 = ?
Option 1: 48
Option 2: 70
Option 3: 14
Option 4: 59
Correct Answer: 70
Solution : Here, in the given equations, we have–
2 + 4 + 6 = 48 ⇒ 2 x 4 x 6 = 48 3 + 2 + 8 = 48 ⇒ 3 x 2 x 8 = 48
Here, from the above two equations we can
Question : If $2s = a + b + c$, then the value of $s(s - c) + (s - a)(s - b)$ is:
Option 1: $ab$
Option 2: $abc$
Option 3: $0$
Option 4: $\frac{a+b+c}{2}$
Correct Answer: $ab$
Solution : Given: $2s = a + b + c$ ⇒ $s = \frac{a\:+\:b\:+\:c}{2}$ Now, $s(s - c) = (\frac{a\:+\:b\:+\:c}{2})(\frac{a\:+\:b\:+\:c}{2}-c)$ ⇒ $s(s - c) =(\frac{a\:+\:b\:+\:c}{2})(\frac{a\:+\:b\:-\:c}{2})$ Also, $(s - a)(s - b) = (\frac{a\:+\:b\:+\:c}{2}-a)(\frac{a\:+\:b\:+\:c}{2}-b)$ ⇒ $(s - a)(s - b) = (\frac{b\:+\:c\:-\:a}{2})(\frac{a\:+\:c\:-\:b}{2})$ So, $s(s - c) + (s
Question : Possible measures of the three angles of a triangle are:
Option 1: 33°, 42°, and 115°
Option 2: 40°, 70°, and 80°
Option 3: 30°, 60°, and 100°
Option 4: 50°, 60°, and 70°
Correct Answer: 50°, 60°, and 70°
Solution : The sum of the angles of a triangle is 180°. Here, 50° + 60° + 70° = 180° Hence, the correct answer is '50°, 60°, and 70°'.
