The sum of the two digit number and the number obtained by interchanging the digit is 132 the digit in the tens place is 2 more than the digit in the unit place. Find the original Number.

▸ⁿᵒ ˢᵖᵃᵐˢ
▹ⁿᵒ ˡⁱⁿᵏˢ ​

Step-by-step explanation:

Let unit's digit be :- y

Let ten's digit be :- x

So, the number formed will be = 10x + y

After interchanging the number we get = 10y + x

The sum of the number = 10x + y

The sum of digits = x + y

According to the question,

➙ ( 10x + y ) + ( 10y + x ) = 132

➙ 11x + 11y = 132

➙ 11 ( x + y ) = 132

➙ x + y = 12 (1)

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
