Answer third question fastt
With explanation

Answer 1

Answer:

Step-by-step explanation:

Also give total observation = 9

First 5 = 25

Last 5= 27

a+b+c+d+e/5= 25

a+b+c+d+e=25x5=125

a+b+c+d=125-e

E+g+h+i+j/5=27

E+g+h+I+j = 27x 5 = 135

All numbers mean = 30

a+b+c+d+e+g+h+I+j=30x10

(125-e)+135=300

-e= 300 -135 -125

-e=300 -260

-e= 40

E=-40

U cancelled 9 but 9 is essential
