Answer:
86.67 will come in place of the "?".
Step-by-step explanation:
Let the question mark be x
Therefore, 400-x% of 375 = 75
Or, 400-x/100×375 = 75
Or, 400-x/4×15 = 75
Or, 400-15x/4 = 75
Or, 1600-15x/4 = 75
Or, 1600-15x = 75 × 4 = 300
Or, -15x = - 1300
Or, 15x = 1300
Or, x = 1300/15 = 86.67.(answer).
