Step-by-step explanation:
<u><em>The question in English is</em></u>
The arithmetic mean of 3 numbers is 24. The second number is 50% greater than the first and the third is one third greater than the second. What are the numbers?
Let
x---> the first number
y ---> the second number
z ---> the third number
we know that
The arithmetic mean of 3 numbers is 24
so

----> equation A
The second number is 50% higher than the first
Remember that

so
----> equation B
The third number is is one third greater than the second
Remember that

so
----> equation C
substitute equation B and equation C in equation A

solve for y

Find the value of x

Find the value of z

therefore
The numbers are
16,24 and 32
