Answer 2

Given that: The unit's digit of a two digit number is 6.

The sum of the number and the number formed on reversing the digits is 99.

Need to find : The number.

Solution :

☀ Let's say that the tens digit of the no. is 'y'.

ATQ,

Number so formed will be :

10 × y + 6

➡ 10y + 6

Number formed after reversing :

6 × 10 + y

➡ 60 + y

___________

T H E R E F O R E ,

Actual number + reversed number = 99

⇒ ( 10y + 6 ) + ( 60 + y ) = 99

⇒ ( 10y + y ) + ( 60 + 6 ) = 99

⇒ 11y + 66 = 99

⇒ 11y = 99 - 66

⇒ 11y = 33

⇒ y = 33/11

$\boxed{\bf{y = 3}} \: \: \bigstar$

∴ Actual number = ( 10 × 3 + 6 )

= 30 + 6

= 36

• Henceforth, the number is 36.
