Answer 2

Answer:

34

Note:

★ Average of observations is given as ;

Sum of total observations

Av. = ------------------------------------------

Total number of observations

Solution;

Here,

It is given that ;

Av. of 15 nos. = 35

=> Sum of 15 nos. / 15 = 35

=> Sum of 15 nos. = 35×15

=> Sum of 15 nos. = 525

Now,

Sum of remaining 13 nos. after removing the two nos. 36 and 47 = 525 - (36 + 47)

= 525 - 83

= 442

Now ,

Av. of remaining 13 nos.

= (Sum of remaining 13 nos.)/13

= 442/13

= 34

Hence ,

The required answer is 34 .
