Answer:

The value of x is 85.

Step-by-step explanation:

We know

Sum of all observations/ No. of observations = Mean

∴ (x) + (x  + 3) + (x + 5) + (x + 7) + (x + 10)/ 5 = 90

⇒x + x + 3 + x + 5 + x + 7 + x + 10 = 450

⇒5x + 25 = 450

⇒5x = 425

⇒x = 85

If you find any mistake, please let me know in the comments :)

Hope this helps!

Answer:

x = 85

Step-by-step explanation:

Mean = Sum of observatins / Total number of observations

So mean = (x + x+3 + x+5 + x+7 + x+10) / 5 = 90

=> (5x+25) / 5 = 90

=> 5x+25 = 450

=> 5x = 425

=> x = 85
