Question

consider the following series of arithmetic expressions.
a = 15
b = 5
c = 3
a = a + 25 / b
b++
c = c - 40 / a
which of the following statements is true?
a == 8 and b == 5 and c == 3.7
a == 20 and b == 6 and c == 1
a == 20 and b == 5 and c == 3.7

Explanation:

Step1: Calculate new value of \(a\)

Given \(a = 15\), \(b = 5\). Using \(a=a + 25/b\), substitute values: \(a=15+\frac{25}{5}=15 + 5=20\)

Step2: Calculate new value of \(b\)

Using \(b++\) (post - increment). Initial \(b = 5\), new \(b=5 + 1=6\)

Step3: Calculate new value of \(c\)

Given \(c = 3\), \(a = 20\). Using \(c=c-\frac{40}{a}\), substitute values: \(c=3-\frac{40}{20}=3 - 2=1\)

Answer:

a == 20 and b == 6 and c == 1
