⠀⠀⠀⠀⠀⠀Answer
➛ Let the score gained in interview part = x
➛ Let the score gained in written part = x+15
⠀
Given:-
➛ Total scores gained = 155
⠀
(We have to find the value of x first)
⠀
● According to the question
➛ (x + 15) + x = 55
➛ 2x + 15 = 155
➛ 2x = 155 - 15
➛ 2x = 140
➛ x = 140/7
➛ x = 70
⠀
⠀
Now,
Scores gained in written part
➛ x + 15
➛ 70 + 15
➛ 85
⠀
Scores gained in interview part
➛ x
➛ 70
⠀
⠀
★Scores gained in written part = 85
★Scores gained in interview part = 70
