Question

question no.14 please​

Answer 1

Answer:

62

Step-by-step explanation:

let digit at tens place be 3x

and digit at one's place be x

then,

according to question

10(3x) + x - (10x + 3x) = 36

31x - 13x = 36

18x = 36

x = 2

no. required = 10(3*2) + 2

60 + 2

= 62

Answer 2

Answer:

62

Step-by-step explanation:

Let the no. be 10x+y

x=3y

when digits are interchanged the no. becomes=  10y+x

10x-x+y-10y= 36

9x-9y=36

x-y=4

we know x=3y

Therefore

3y-y=4

2y=4

y=2

x=3y=6

Therefore the no. is 62
