Let the numbers be a, b, c, d, e, f. Given: a+b+c = 84, and c+d+e+f? Wait—careful: "last three numbers" means d, e, f? No, six numbers total, so "last three" = 4th, 5th, 6th? Actually, if there are six numbers, "last three" are the 4th, 5th, and 6th. But then we don't have enough info. Reread: They say "the sum of all six numbers is 180." And "average of first three = 28" → sum first three = 84. "Average of last three = 32" → sum last three = 96. But the third number is counted in both sums. So 84 + 96 = 180 includes the third number twice. Thus, 180 = (sum of all six) + (third number). So 180 = 180 + third number → third number = 0.
4. Step-by-Step Strategy to Study "SASMO Practice Papers Full"
In SASMO, 90 minutes for 25 questions sounds generous—until you face a tricky combinatorics or geometry puzzle. The average student spends 3–4 minutes per question, but difficult problems can consume 10+ minutes. Full papers teach you the art of "strategic skipping": knowing when to move on and return later. sasmo practice papers full
While the exam adapts to each grade level, SASMO consistently tests specific mathematical domains. When analyzing full practice papers, look out for these core areas:
