Question

If the mean of x x/2. x/5 x/4 x/3 is 10 then
find the value of x​

Answer 1

Step-by-step explanation:

∣x+2x−4xx+3∣∣∣∣∣∣=∣∣∣∣∣∣4−225∣∣∣∣∣∣

Since both have the same order, we can eqaute the corresponding rows and columns respectively.

x+2=4⇒x=4−2=2

x=2

⇒x−4=−2⇒x=−2+4=2

⇒x+3=5⇒x=5−3=2

∴x=2
