MEAN :

SUM OF ALL NO. / TOTAL NO.

6 + 10 + 11 + X + 12 + Y / 6

39 + X + Y / 6

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

BUT MEAN = 10

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

10 = 39 + X + Y / 6

10 * 6 = 39 + X + Y

60 = 39 + X + Y

X + Y = 60 - 39

X + Y = 21 .................... equation 1

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

Y IS 7 MORE THAN X

Y = X + 7

SUBSTITUTE THIS VALUE IN EQUATION 1

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

X + X + 7 = 21

2X + 7 = 21

2 X = 21 - 7

2X = 14

X = 14 / 2

X = 7

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

Y = X + 7

Y = 7 + 7

Y = 14
