Question

Sachin Tendulkar in his 17th inning makes a score of 85 and thereby increases average by 3. what is his average after the 17th inning.​

Answer 1

The average score after 17th inning would be 37

Step-by-step explanation:

Let x be the average in 16 innings,

∵ Sum of observations = number of observations × their average

So, total score in 16 innings = 16x,

Now, score in 17th inning = 85,

i.e. total score in 17 innings = total score in 16 innings + score in 17th inning

= 16x + 85

Again if the average 17 innings is x + 3,

Then total score = 17(x+3)

If 16x + 85 = 17(x + 3)

16x + 85 = 17x + 51

85 - 51 = 17x - 16x

34 = x

Hence, the average score after the 17th inning = 34 + 3 = 37.

Answer 2

Answer:

37

Step-by-step explanation:

Let the average of Sachin's of the 16th inning be x.

Then, the sum of the 17 innings = 16x + 85 and

(16x + 85) = 17(x + 3)

x = 85 - 51 = 34

Average of 17 innings = 34 + 3 = 37

SO, THE ANSWER IS 37
