3 sweets = 335 left
5 sweets = 307 short
Of he were to give every student 2 more sweets (increment from 3 to 5 is 2), he would need 642 sweets.
Hence, number of student = 642 sweets divide by 2 = 321 students
321 students x 3 sweets + 335 left = 1298
OR
321 students x 5 sweets - 307 short = 1298
5 sweets = 307 short
