Question

A number consist of 2 digits. The digit at the unit place is 3 times the digits at tens place. If the 36 is added to the number. The digits are reversed

Answer 1

Step-by-step explanation:

let the tens digit be x

and unit digit be 3x

so the no. is=10x+3x

a/q

if 36 added the no. are reverse

10x+3x+36=30x+x

13x+36=31x

13x-31x=-36

-18x=-36

x=-36/-18

x=2

so tens digit=2

and unit digit=3×2=6

so the no.is

10x+3x

10×2+6

26
