Ето моето решение на тази задача:

function scholaship(input) {
    let income = Number(input.shift());
    let averageGrade = Number(input.shift());
    let minSalary = Number(input.shift());

    let socialScholarship = 0;
    let Scholarship = 0;

    if (income < minSalary && averageGrade > 4.5) {
        socialScholarship = Math.floor(minSalary - (minSalary * 0.65));
    }
    if (averageGrade >= 5.50) {
        Scholarship = Math.floor(averageGrade * 25);
    }

    if (socialScholarship !== 0 || Scholarship !== 0) {
        if (socialScholarship > Scholarship) {
            console.log(`You get a Social scholarship ${socialScholarship} BGN`)
        } else {
            console.log(`You get a scholarship for excellent results ${Scholarship} BGN`);
        }
    } else {
        console.log("You cannot get a scholarship!");
    }
}
