Question : The volume of a sphere is given by 130977 cm3. Its surface area (in cm2) is:
Option 1: 16847
Option 2: 12474
Option 3: 17424
Option 4: 14274
Correct Answer: 12474

Question : Directions: In the following question a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series. $7 \frac{1}{7}, 8 \frac{2}{6}, 9 \frac{5}{5}, 12 \frac{2}{4}, 16 \frac{2}{3},?$
Option 1: $35 \frac{3}{4}$
Option 2: $16 \frac{4}{4}$
Option 3: $\frac{50}{2}$
Option 4: $15 \frac{2}{4}$
