Add: 3.45 + 6.78 + 0.027

This question was previously asked in
SSC CGL 2025 Tier 1 Question Paper (25-Sep-2025) (Shift 3)
The correct answer is

10.257

To add 3.45, 6.78, and 0.027, first align all numbers to the same number of decimal places: 3.450, 6.780, and 0.027.

Adding them column by column: \(3.450 + 6.780 = 10.230\).

Then \(10.230 + 0.027 = 10.257\).

Hence, the answer is 10.257.
