Option 1: 100
Option 2: 98
Option 3: 92
Option 4: 110
Correct Answer: 100
Solution : Given: 124 D 4 C 86 D 2 A 61 A 17 B 3 = ?

Question : Directions: Select the option that is related to the fifth letter cluster in the same way as the second letter cluster is related to the first letter cluster and the fourth letter cluster is related to the third letter cluster. PAG : NYE :: TUB : RSZ :: RICE : ?
Option 1: PGAC
Option 2: SJDF
Option 3: RJDE
Option 4: QHBD
Correct Answer: PGAC
Solution : Given: PAG : NYE :: TUB : RSZ :: RICE : ?
Subtract 2 from the place value of each letter of PAG and TUB to get the respective letter clusters – PAG→P – 2 = N; A – 2 = Y; G – 2

Question : A can do a work in 6 days, which B alone can do in 8 days. In how many days they together can do it?
Option 1: $\frac{24}{7}$ days
Option 2: $\frac{25}{7}$ days
Option 3: $\frac{27}{4}$ days
Option 4: $\frac{22}{3}$ days
Correct Answer: $\frac{24}{7}$ days
Solution : One day's work of A = $\frac{1}{6}$ One day's work of B = $\frac{1}{8}$ One day's work of A and B together = $\frac{1}{6}+\frac{1}{8}$ = $\frac{4+3}{24}$ = $\frac{7}{24}$ $\therefore$ Together they can complete the work in ($1÷\frac{7}{24}$) = $\frac{24}{7}$ days Hence, the correct answer
Question : The volume of the sphere is 38,808 cm3. What is the surface area of the sphere?
Option 1: 4455 cm2
Option 2: 4433 cm2
Option 3: 5544 cm2
Option 4: 3344 cm2
Correct Answer: 5544 cm2
Solution : Given, the volume of the sphere = 38,808 cm3 Let the radius of the sphere be $r$. According to the question, $\frac{4}{3}\pi r^3$ = 38,808 ⇒ $r^3$ = $\frac{38808×3×7}{4×22}$ = 9261 ⇒ $r$ = 21 So, the surface area of the sphere

Question : Which one of the following processes is responsible for the glittering of air bubbles rising through water?
Option 1: Reflection of light
Option 2: Refraction of light
Option 3: Total internal reflection of light
Option 4: Scattering of light
Correct Answer: Total internal reflection of light
Solution : The correct answer is Total internal reflection of light
Due to the total internal reflection, light gets trapped inside the air bubble, making it shine. It occurs when the ray travels from a denser medium to a rarer medium and
