Answer 2

AnswEr:-

Score of Gopi = 10 marks.

Score of Reshmi = 18 marks.

$\rule{200}{1}$

Explanation:-

i) Gopi gets correct answer: 5 & incorrect answer: 5

Hints:-

• 3 Marks are awarded for every correct answer.

• (-1) mark is awarded for every incorrect answer.

Now score of Gopi:-

⇒ Score of Gopi = (5 × 3) + 5 × (-1)

⇒ Score of Gopi = 15 - 5

⇒ Score of Gopi = 10

Therefore,

$\therefore{\underline{\textsf{Score of Gopi ={\textbf{ 10 marks }}}}}$

$\rule{200}{1}$

ii) Reshmi gets correct answer : 7 & incorrect answer : 3

Hints:-

• 3 marks are awarded for every correct answer.

• (-1) mark is awarded for every incorrect answer.

Now score of Reshmi:-

⇒ Score of Reshmi = (7 × 3) + 3 × (-1)

⇒ Score of Reshmi = 21 - 3

⇒ Score of Reshmi = 18

Therefore,

$\therefore{\underline{\textsf{ Score of Reshmi ={\textbf{ 18 marks }}}}}$
