Question

the mean of 15 numbers is 15 if two no. 18 and 12 are excluded then what will be the mean of remaining numbers??

Answer 1

Answer:

15

Step-by-step explanation:

Mean of 15 no.s=15

Sum of the no.s=15×15

No. Excluded=12,18

Therefore, sum of no.s-no. excluded

=225-12-18

=225-30

=195

2no. Excluded

Total no. of no.s =15-2=13

Mean of remaining no.s=195/13=15

Answer 2

answer:- 15

mean of 15 no.s =15

sum of the no.s =15×15

No. excluded = 12,18

= 225-30

= 195

2 no. excluded .

Total no. of no.s = 15-2-13

Mean of remaining no.s=195/13= 15. ans....
