Question

The generalised form of 6789 is

• A. 6000×1 + 700×1 + 80×1 + 9×
• B. 1000×6 + 100×7 + 10×8 + 1×9
• C. 6000+700+80+9
• D. 1×6 + 7×10 + 8×100 + 9×1000

Answer 1

The correct option is B 1000×6 + 100×7 + 10×8 + 1×9

The generalised form of any number abcd is
(1000×a)+(100×b)+(10×c)+(1×d)
So, the generalised form of 6789 is
(1000×6) + (100×7) + (10×8) + (1×9)
Therefore, option b is correct.
