Question : The third proportional to $\left(x^2-y^2\right)$ and $(x-y)$ is:
Option 1: $(x -y)$
Option 2: $\frac{x-y}{x+y}$
Option 3: $\frac{x+y}{x-y}$
Option 4: $(x + y)$
Correct Answer: $\frac{x-y}{x+y}$
Solution : We know, The third proportional = $\frac{\text{(Second proportional)}^2}{\text{(First proportional)}}$ $= \frac{(x-y)^2}{x^2-y^2}$ $= \frac{(x-y)^2}{(x+y)(x-y)}$ $= \frac{(x-y)}{(x+y)}$ Hence, the correct answer is $\frac{(x–y)}{(x+y)}$.

Option 3: UYUC
Option 4: VXVC
Correct Answer: UXVD
Solution : Given: RRMR, STPV, TVSZ, _____, VZYH, WBBL
In the series given above, add consecutive natural numbers to the letters to obtain the next letter cluster. RRMR→R + 1 = S; R + 2 = T; M + 3 = P; R + 4 = V
Question : Directions: Select the figure that can replace the question mark (?) in the following series.
Solution : Given:
In the above–given figure series, the pattern is as follows – 1. The numbers 6 and 9 appear alternatively. 2. The movement of symbols/ numbers is as follows – 6 / 9 – Top right→Top left→Bottom centre→Top right @ – Bottom centre→Top right→Top left→Bottom centre
Question : Two circles of diameters 10 cm and 6 cm have the same centre. A chord of the larger circle is a tangent of the smaller one. The length of the chord is:
Option 1: 4 cm
Option 2: 8 cm
Option 3: 6 cm
Option 4: 10 cm
Correct Answer: 8 cm
Solution : OE = 3 cm OC = OD = 5 cm We know tangent is perpendicular to the radius at its point of contact with the circle. So, OE $\perp$ CD Using Pythagoras theorem in $\triangle$ EOC, CE2 = OC2 – OE2
Question : If $\theta+\phi=\frac{\pi}{2}$ and $\sin\theta=\frac{1}{2}$, then the value of $\sin\phi$ is:
Option 1: $1$
Option 2: $\frac{1}{\sqrt{2}}$
Option 3: $\frac{1}{2}$
Option 4: $\frac{\sqrt{3}}{2}$
Correct Answer: $\frac{\sqrt{3}}{2}$
Solution : $\theta+\phi=\frac{\pi}{2}=90°$---------(i) Also, $\sin \theta = \frac{1}{2}=\sin 30°$ $⇒\theta =30°$ Putting $\theta = 30°$ in (i), we get: $30° + \phi=90°$ $⇒\phi=60°$ So, $\sin \phi= \sin 60° = \frac{\sqrt{3}}{2}$ Hence, the correct answer is $\frac{\sqrt{3}}{2}$.
