Estimation Numerical Reasoning Question
Estimate (to the nearest 100): 194 + 180 + 343
A≈ 800
B≈ 1,000
C≈ 500
D≈ 700
E≈ 600
Worked solution
Round to one or two leading digits, compute, and match the order of magnitude. The correct answer is ≈ 700. Traps to avoid: ≈ 800 comes from the "rounded up too far" error; ≈ 1,000 comes from the "wrong place value" error; ≈ 500 comes from the "under estimate" error; ≈ 600 comes from the "rounded down too far" error.
