Question : There are 500 guests at an event, among whom 28% are adult males, 64% are adult females, and the rest are children. Could you find the total number of children at the event?
Option 1: 55
Option 2: 45
Option 3: 40
Option 4: 50
Correct Answer: 40
Solution : According to the question ⇒ Percentage of children = 100% − (28% + 64%) = 100% − 92% = 8% Now, Number of children = $\frac{8}{100}$ × 500 = 0.08 × 500 = 40 Hence, the correct answer is 40.
Question : Directions: A & B means A is the wife of B; A # B means A is the father of B; A @ B means A is the son of B; A % B means A is the husband of B; A + B means A is the mother of B. If A & B # C & D @ E % F + G, then how is D related to G?

Solution : Given: A & B means A is the wife of B. A # B means A is the father of B. A @ B means A is the son of B. A % B means A is the husband of B. A + B means
Question : Directions: In the following question a series is given, with one number missing. Choose the correct alternative from the given ones that will complete the series. 19, 28, 39, 52, ?, 84
Option 1: 39
Option 2: 52
Option 3: 67
Option 4: 84
Correct Answer: 67
Solution : Given: 19, 28, 39, 52, ?, 84
Add consecutive odd numbers to the previous number to obtain the next number. 19 + 9 = 28; 28 + 11 = 39; 39 + 13 = 52; 52 + 15 = 67; 67 + 17 = 84
Question : Directions: Select the correct mirror image of the given figure when the mirror is placed at MN as shown.

Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on line MN). So, the left side of the reflected image will appear
Question : If $x\sin^{3}\theta +y\cos^{3}\theta=\sin\theta\cos\theta$ and $x\sin\theta-y\cos\theta=0$, then the value of $\left ( x^{2}+y^{2} \right )$ equals:
Option 1: $1$
Option 2: $\frac{1}{2}$
Option 3: $\frac{3}2$
Option 4: $2$
Correct Answer: $1$
Solution : Given: $x\sin\theta=y\cos\theta$ And, $x\sin^{3}\theta +y\cos^{3}\theta=\sin\theta\cos\theta$ ⇒ $x\sin\theta(\sin^{2}\theta) +y\cos\theta(\cos^{2}\theta)=\sin\theta\cos\theta$ Since, $x\sin\theta=y\cos\theta$ and $\sin^{2}\theta+\cos^{2}\theta=1$, So, $x\sin\theta=y\cos\theta=\sin\theta\cos\theta$ ⇒ $x=\cos\theta$ and $y=\sin\theta$ So, $x^{2}+y^{2}=\sin^{2}\theta+\cos^{2}\theta=1$ Hence, the correct answer is 1.
