Answer»

Marks secured = 86.4% of 500 = 86.4/100 × 500 = 432

Marks secured in Mathematics = 22.22% of 432 ≅ 96

Remaining marks = 432 - 96 = 336

Marks secured in Science = Marks secured in English = 25% of 336 = 0.25 × 336 = 84

Remaining marks = 336 - (84 + 84) = 168

? Equal marks are secured in Hindi, COMPUTERS and ARTS,

∴ Marks secured in Hindi = 168/3 = 56
