Answer:
Answer will be 113,,,,(according to me)
Step-by-step explanation:
Average of 11 results = 18
Total Mean of 11 resuls = 11×18=298
A/Q
Total mean of first five results = 5×17=85
Similarly, Total mean of last five results = 5×20= 100
Now, 6th Results=Total mean of 11 results -(Total mean of first five results + Total mean of last five results)
=>298-(85+100)
=>298-185
=>113(Answer)
