First option: SU; S + 2 = U
Second option: BD; B + 2 = D
Third option: IK; I + 2 = K
Fourth option: PN; P – 2 = N

So, the fourth option is different from the

Correct Answer: 2

Solution : $2(\tan ^2 A \cos ^2 A+\cos ^2 A)$
= $2\cos ^2 A(\tan ^2 A + 1)$
= $2\cos ^2 A×\operatorname{sec}^2A$
= $2\cos ^2 A×\frac{1}{\cos^2A}$
= $2$
Hence, the correct answer is 2.

Correct Answer: 48

Solution : Given: Third proportion to 10 and X = 90
⇒ 10 : X : : X : 90
⇒ $\frac{10}{X} = \frac{X}{90}$
⇒ $X = \sqrt{10 \times 90} = 30$
Similarly, the third proportion to 12 and Y = 27
⇒ 12 : Y :

Correct Answer: 9

Solution : Given, $l+m+n=0$
$(\frac{l^2}{mn}+\frac{m^2}{nl}+\frac{n^2}{lm})^2$
$= (\frac{l^3+m^3+n^3}{lmn})^2$
We know, if $l+m+n=0$, then $l^3+m^3+n^3=3lmn$
$= (\frac{3lmn}{lmn})^2$
$= 9$
Hence, the correct answer is 9.

Correct Answer: 40 km/hr

Solution : Total journey = 400 km
Speed of the car for $\frac{3}{4}$th journey = 30 km/hr
$\frac{3}{4}$th journey= $400\times(\frac{3}{4})$km = 300 km
Remaining journey = 400 – 300 = 100 km
Let the speed of the car for the rest of the journey be $x$
