Question : Directions: Select the option that is related to the third letter cluster in the same way as the second letter cluster is related to the first letter cluster. SUN : QSL :: ROP : ?
Option 1: PMM
Option 2: PMO
Option 3: PMN
Option 4: PNN
Correct Answer: PMN
Solution : Given: SUN : QSL :: ROP : ?
Subtract 2 from the place value of each letter of SUN to obtain the related letter cluster. S – 2 = Q; U – 2 = S; N – 2 = L Thus, SUN is related to
Question : Find the value of $k$, if $13 - [10 - \{16 + 8 \div(k - 2)\} + 2] = 20$
Option 1: $\frac{14}{3}$
Option 2: $\frac{31}{3}$
Option 3: $\frac{40}{13}$
Option 4: $\frac{23}{13}$
Correct Answer: $\frac{14}{3}$
Solution : $13-[10-\{16+8 \div(k-2)\}+2] = 20$ ⇒ $13-[10-{16-\frac{8}{k-2}}+2] = 20$ ⇒ $13-[10-\{\frac{16k-32+8}{k-2}\}+2] = 20$ ⇒ $13-[\frac{10k-20-16k+32-8+2k-4}{k-2}]=20$ ⇒ $13-[\frac{-4k}{k–2}] = 20$ ⇒ $13+\frac{4k}{k–2} = 20$ ⇒ $13k-26+4k = 20k-40$ ⇒ $3k = 14$ ⇒ $k = \frac{14}{3}$ Hence, the correct answer is $\frac{14}{3}$.

Option 1: Troposphere
Option 2: Ionosphere
Option 3: Stratosphere
Option 4: Mesosphere
Correct Answer: Stratosphere

Question : The number of solid spheres, each of diameter 6 cm, that could be moulded to form a solid metal cylinder of height 90 cm and diameter 4 cm is:
Option 1: 10
Option 2: 14
Option 3: 16
Option 4: 13
Correct Answer: 10
Solution : We have, The radius of the sphere, $R$ = 3 cm The radius of the cylinder, $r$ = 2 cm The height of the cylinder, $h$ = 90 cm Now, the required number of solid spheres = $\frac{\text{ Volume of the cylinder}}{\text{Volume of the Sphere}}$
