Question

What number will be output by the console.log command on line 5?

A. 10
B. 25
C. 30
D. 35

Answer 1

The output is 35

Step-by-step explanation:

Required

Determine the output on line 5

We start by analysing the program line by line.

On line 1: kit = 20

On line 2: roo = 10

On line 3: kit = kit + 5

Substitute 20 for kit.

So, we have

kit = 20 + 5

kit = 25

On line 4:

roo = kit + roo

Substitute values for kit and too

roo = 25 + 10

roo = 35

On line 5: Output roo

So, 35 is displayed as an output
