Answer 2

Answer:

BRAINLIEST

Step-by-step explanation:

let the number of correctly attempted questions be x

so, the number of unattempted or wrong question = 180-x

total marks for correct attemptions = 4x

and total marks for unattempeted or wrong question = -1 (180-x)

= x - 180

as total marks = sum of attempted and unattempted or wrong question = 180-x

450 = 4x + x - 180

450 = 5x -180

630 = 5x

126 = x

so, the number of THE correctly attempted question was 126.
