Step-by-step explanation:

Q7. 1)

Average of 1st 6 EVEN NUMBER:-

1st step:

Find 1st 6 even numbers... which are:

2,4,6,8,10,12

2nd step:

Add those numbers and divide those numbers by 6(because there are 6 numbers)

3rd step:

2 + 4 + 6 + 8 + 10 + 12= 42

42 ÷ 6 = 7

THUS THE AVERAGE OF 1ST 6 EVEN NUMBER IS 7.

Q7. 2)

1st step:

add all the Marks and divide it by 8 (because there are marks of 8 students)
