. Assume that Ezekiel's marks in Mathematics out of 100 is z. Anshad got 13 more than one-third of the marks of Ezekiel and Ferliza got 8 marks less than twice the marks of Ezekiel. If Ezekiel's marks is 4 less than twice the marks of Kavita. Write the expressions for the marks of Anshad, Ferliza and Kavita in terms of z.
Answers & Comments
Above answer contain correct worfs
The required expressions are
Anshad's marks = (z + 39)/3
Ferliza's marks = 2z - 8
Kavita's marks = (z + 4)/2
Given:
Assume that Ezekiel's marks in Mathematics out of 100 is z
Anshad got 13 more than one-third of the marks of Ezekiel and Ferliza got 8 marks less than twice the marks of Ezekiel. Ezekiel's mark is 4 less than twice the marks of Kavita.
To find:
If Ezekiel's mark is 4 less than twice the marks of Kavita. Write the expressions for the marks of Anshad, Ferliza, and Kavita in terms of z.
Solution:
Given that Ezekiel's marks in Mathematics are z
Let 'x', 'y', and 'v' be the Anshad, Ferliza, and Kavita marks
Anshad got 13 more than one-third of the marks of Ezekiel
=> x = [ 1/3 (z) + 13 ]
=> x = [ z/3 + 13 ]
=> 3x = z + 39
=> x = (z + 39)/3
Ferliza got 8 marks less than twice the marks of Ezekiel.
=> y = 2z - 8
Ezekiel's mark is 4 less than twice the marks of Kavita.
=> z = 2v - 4
=> 2v = z + 4
=> v = (z + 4)/2
Therefore,
The required expressions are
Anshad's marks = (z + 39)/3
Ferliza's marks = 2z - 8
Kavita's marks = (z + 4)/2
