Show answer & explanation
Correct answer: C
To solve this problem, we first extract the runs scored by each of the five batsmen from the bar graph:
A: 95 runs
B: 105 runs
C: 135 runs
D: 75 runs
E: 145 runs
Step 1: Calculate J1, J2, and J3
J1 (Average runs):
J1 = (95 + 105 + 135 + 75 + 145) / 5
J1 = 555 / 5 = 111
J2 (Difference between E and D):
J2 = 145 - 75 = 70
J3 (Difference between C and B):
J3 = 135 - 105 = 30
Step 2: Calculate (J3 - J2 + J1)
Now, substitute the values into the given expression:
Value = (30 - 70 + 111)
Value = (-40 + 111)
Value = 71
The final value is 71, which corresponds to Option C.
