Question

the digit in the tens place of a two digit number is three times the digit in units place if the digits are reversed the new number will be 36 less than the original number find the number
​

Answer 1

Answer:

62

Step-by-step explanation:

Let the digit in one's place will be = x

So, the digit in ten's place will be = 3x

The number formed will be = 10(3x) + x = 31x

On reversing the digits we get = 10(x) + 3x = 13x

ATQ,

31x - 13x = 36

= 18x = 36

= x = 2

The number will be = 31x = 62

Answer 2

Answer:

let original number be

10x+y

the digit in ten s place is 3 time than the units place

3*10x+y=30x+y

when the no is reversed then

10y+x

the difference is....

30x+y-(10y+x)=36

30x + y-10y-x=36

29x-9y=36
