Answer:
Amir's mass is 48 kg.
Explanation:
Let's assume the mass of Anson is x kg.
According to the given information:
Ali is 7 kg heavier than Anson, so Ali's mass is x + 7 kg.
Amir is 6 kg lighter than Anson, so Amir's mass is x - 6 kg.
The total mass of all three individuals is 163 kg:
Anson + Ali + Amir = x + (x + 7) + (x - 6) = 3x + 1 = 163
Now, we can solve this equation to find the value of x, which represents Anson's mass:
3x + 1 = 163
3x = 162
x = 54
Therefore, Anson's mass is 54 kg.
To find the mass of Amir, we substitute x = 54 into the expression for Amir's mass:
Amir = x - 6 = 54 - 6 = 48
Hence, Amir's mass is 48 kg.
Hope it helps!! :)
