Question

If the digits at unit place is ‘m’ and digit at tens place is ‘n’, then what is the two digit number obtained by reversing the digits?​

Answer 1

Answer:

The reversed number is mn.

Units place of the Reversed number = n.

Tens place of the Reversed number = m.

Step-by-step explanation:

Given :

Digit at unit's place = m

Digit at ten's place = n

To Find :

The two digit number obtained by reversing the digits.

Procedure :

The original number is 'nm'.

∵ n is at the ten's place and m is at the unit's place.

Hence the reversed number is mn.

Units place of the Reversed number = n.

Tens place of the Reversed number = m.

Answer 2

Solution :-

given that,

• Unit place = m
• tens place = n .

so,

→ Two digits number is = 10 * tens place + unit place = 10*n + m = (10n + m) .

now give that, digits are reversed .

then we have,

• unit place = n .
• tens place = m .

therefore,

→ Two digits number = 10 * tens place + unit place = 10*m + n = (10m + n) . (Ans.)

Hence, the two digit number obtained by reversing the digits is (10m + n) .
