Correct Answer: psmjst

Solution : Given:
jtm_r_ jt_prs_tmpr_ j_mprs

To fill the series we have to divide the series – jtm_r_ / jt_prs / _tmpr_ / j_mprs

Let's check each option –
First option: psmjst; jtmprs / jtmprs / jtmprs / jt

Correct Answer: $\frac{x-1}{x+2}$

Solution : $\frac{x^2-3 x+2}{x^2-4}$
= $\frac{(x-2)(x-1)}{(x-2)(x+2)}$
= $\frac{(x-1)}{(x+2)}$
Hence, the correct answer is $\frac{(x-1)}{(x+2)}$.

Correct Answer:

Solution : As per the mirror image properties, closer things appear close to the mirror in the reflection.
Here, according to the information provided, the mirror is placed on the bottom side of the figure (on line AB). So, the top side of the reflected image will appear

Correct Answer: 105

Solution : Let the usual time, speed, and distance be $t$ hours, $u$ km/hr, and $d$ km, respectively.
$\frac{d}{u}=t$
Time taken by current speed – time taken by usual speed = $\frac{15}{60}$
$⇒\frac{d}{u}-\frac{d}{\frac{7u}{6}}=\frac{15}{60}$
$⇒t-\frac{6t}{7}=\frac{1}{4}$
$⇒\frac{t}{7} =\frac{1}{4}$
$⇒t=\frac{7}{4}$ hours
$\therefore t=\frac{7}{4}\times 60= 105$ minutes
Hence, the correct answer

ISLAND is written as HTKBME –

Subtract and add 1 alternately to the place value of each letter of ISLAND to obtain the required code –
I – 1 = H; S + 1 = T; L – 1 = K; A + 1

Correct Answer: $-\sqrt{3}$

Solution : Given: $\tan \theta \cdot \tan 2 \theta=1$
$⇒\tan2\theta=\cot\theta$
$⇒\tan2\theta=\tan(90°- \theta)$
$⇒2\theta=90°- \theta$
$⇒3\theta=90°$
$\therefore \theta=30°$
$\cot 5\theta=\cot(5×30°)=\cot 150°=\cot(90°+60°)=-\tan60°=-\sqrt3$
Hence, the correct answer is $-\sqrt3$.

Correct Answer: 1000

Solution : Given:
11 : 1210 :: 10 : ?

11² = 121 and 121 × 10 = 1210
Similarly, 10² = 100 and 100 × 10 = 1000

Hence, the third option is correct.
