Answer 2

Given :-

• A two digit number.
• Ten's place digit is 3 more than the unit's place digit.
• Digit at unit place is b.

--------------------------------------------------

To Find :-

• What is the number ?

--------------------------------------------------

Solution :-

As we know that

A two digit number is 10 × digit in ten’s place + digit in unit’s place.

➟ Ten's place digit = 3 more than b

➟ Ten's place digit = ( b + 3 )

Now the number will be

→ 10 × (ten's digit) + unit's digit

→ 10 × (b + 3) + b

→ 10b + 30 + b

→ 30 + 11b

Hence, the two digit number is 30 + 11b.
