| If the correct numbers are given as fractions with denominator 150 (oe fraction), only withhold the mark in the first instance | |
| If the three values inside the circles sum to 150, award the 4th mark for 0 written outside the circles, but not for no value written | |
| If the three values inside the circles sum to more than 150, the 4th mark cannot be awarded on ft |
