Hey bro !!
Here is your answer..
M + Z = 75
M - Z = 1.4
____________
2M = 76.4
M = 76.4/2
M = 38.2
Median = 38.2
M + Z = 75
Z = 75 - M
= 75 - 38.2
= 36.8
Z = 36.8
Mode = 36.8
Z = 3M - 2X
36.8 = 3(38.2) - 2X
36.8 = 114.6 - 2X
2X = 114.6 - 36.8
2X = 77.8
X = 77.8/2
X = 38.9
mean = 38.9
Hope it helps you......
THANKS
