Question

which number will be formed, by we interchanging the digits at unit's and hundreds place in 123? is the new number greater or smaller than 123?​

Answer 1

Solution :-

given number is 123 .

So,

→ 123 = 1 * 100 + 2 * 10 + 3 * 1

as we can see that,

→ Hundreds place digit = 1

→ Ten's place digit = 2

→ Unit's place digit = 3

now, interchanging the digits at unit's and hundreds place we get,

→ Hundreds place digit = 3

→ Ten's place digit = 2

→ Unit's place digit = 1

then new number ,

→ 3 * 100 + 2 * 10 + 1 = 300 + 20 + 1 = 321

as we can see that,

→ 3 > 2

→ Digits as hundreds place of new number > Digits as hundreds place of given number .

therefore,

→ 321 > 123 .

Hence, The number is greater than 123 .
