Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

so here we go

Step-by-step explanation:

now let total correct answers be x,total incorrect be y and that of unattempted be z

so now here total questions =20

according to first condition

x+y+z=20 (1)

also here total correct questions=3

so x=3 (2)

now according to second condition

5x-3y=3 (3)

substitute x ka value in (3)

we get

15-3y=3

ie -3y=-12

ie y=4

so

then substitute value of x and y in (1)

we get 7+z=20

ie z=13

hence simran got 4 incorrect answers

and she didnt attempted 13 answers
