96. The aggregate score of 3 cricketers A, B, C was 149. What was the score of each cricketer?
B and C together made 76 runs.
A and C together made 103 runs.
(A) If statement 1 alone is sufficient but statement 2 alone is not sufficient.
(B) If statement 2 alone is sufficient but statement 1 alone is not sufficient.
(C) If both statements 1 and 2 together are sufficient but neither of statements alone is sufficient.
(D) If statements 1 and 2 together are not sufficient.
Answer:
(C) If both statements 1 and 2 together are sufficient but neither of statements alone is sufficient.
Explanation:
The main premise gives $A + B + C = 149$. Statement 1 gives $B + C = 76$. Substituting this into the main premise yields $A = 149 – 76 = 73$. With $A$ known, Statement 2 ($A + C = 103$) allows us to find $C = 30$. Finally, we substitute $C$ back to find $B = 46$. Thus, we need both statements working together to solve for all three variables.
97. When we want to calculate the spread of a group of scores it is referred to as ?

Explanation:
Mean and median measure central tendency. The standard deviation is the primary, most comprehensively used statistical metric to calculate and express the “spread” or dispersion of a group of scores around their mean. (Range is a simpler measure of spread, but standard deviation is mathematically referred to as the definitive calculation).

Answer:
(A) 1 hour 36 minutes
