Answer:
84
Step-by-step explanation:
Let's say Nick gets amount N, Angad amount A, and June amount J.
Here's what we know:
A+N+J=140
A=2*N
N=3*J.
Let's plug these values in.
N=3*J, so A+N+J=140 can now be A+3*J+J=140.
A=2*N, and N=3*J, so A=2*3*J=6*J. Then, A+3*J+J=140 is now 6*J+3*J+J=140, so 10*J=140 and J=14. N = 3*J=42 and A=2*N=84. Checking this, 14+42+84=140, so we are good to go!

Answer:
Formula for mean in grouped data
= Zfx/ Zf
f = sum of the number of mice
= 35
Frequency = 39 + x
Mean = 7
Fx = 20 + 78 + 112 + 8x + 54
= 264 + 8x
7 = 264 + 8x/ 39 + x
7(39+x) = 264 + 8x
After solving you will get
x = 9
Hope this helps.
