Let's find the differences between the given scores step-by-step. To do this, we'll subtract the scores one from the other as specified in each part of the question.
(a) Difference between Junaid and Zia:
Junaid's Score = 65,029
Zia's Score = 6,853
Difference = 65,029 - 6,853 = 58,176
So, the difference between Junaid and Zia's scores is 58,176.
(b) Difference between Hassan and Ali:
Hassan's Score = 7,120
Ali's Score = 4,002
Difference = 7,120 - 4,002 = 3,118
So, the difference between Hassan and Ali's scores is 3,118.
(c) Difference between Junaid and Hassan:
Junaid's Score = 65,029
Hassan's Score = 7,120
Difference = 65,029 - 7,120 = 57,909
So, the difference between Junaid and Hassan's scores is 57,909.
(d) Difference between Zia and Ali:
Zia's Score = 6,853
Ali's Score = 4,002
Difference = 6,853 - 4,002 = 2,851
So, the difference between Zia and Ali's scores is 2,851.
These calculations help us understand how the scores of each pair relate to each other by determining the numerical difference between them. Calculating differences like this can be useful in a variety of contexts, such as determining standings in a competition or understanding achievement gaps.
