Answer 1

The correct option is B 6,05,80,932 < 6,08,80,932 < 6,50,08,932 < 6,50,80,932

In ascending order we arrange the numbers from the smallest to the greatest.

All the given numbers have equal number of digits. Also all the numbers have 6 in the crore's place.

In the ten lakh's place, the numbers, 6,05,80,932 and 6,08,80,932, have zero, while the numbers 6,50,80,932 and 6,50,08,932 have 5.

Hence, 6,05,80,932 and 6,08,80,932 are smaller than 6,50,80,932 and 6,50,08,932.

Between 6,05,80,932 and 6,08,80,932, the lakh's place has different digits. In 6,05,80,932, it is 5, while in 6,08,80,932, it is 8.
Hence 6,05,80,932 < 6,08,80,932.

Between 6,50,80,932 and 6,50,08,932, the ten thousand's place has different digits.

In 6,50,80,932, it is 8, while in 6,50,08,932, it is 0.
Hence 6,50,08,932 < 6,50,80,932

Hence, 6,05,80,932 is the smallest, while 6,50,80,932 is the greatest.

Therefore
6,05,80,932 < 6,08,80,932 < 6,50,08,932 < 6,50,80,932 is the correct option.
