The digit at the tens place of a two digit number is three times the digit at the ones place.if the sum of the number and the number formed by reversing

the digits is 88 find the number


The Brainliest Answer!
there are two ways you can answer it
let the unit digit be x
and the ten's digit be y
so the no is 10y+x
after reversing it :10x+y
adding both the nos
we get:11x+11y=88
⇒x+3x=8   (from eqn (i)_)
so the no is 62

another method
2).its a bit of hit nd trial method ,
  the possible two digits no where ten's digit is thrice the unit's digit are:
 62 and 93
on reversing 93 and adding 39 we dont get 88
so the answer is 62

Let the digit in the tens place be x and digit in the ones place be y.                             so,original number                                           = 10x+y                                                number when digits are interchanges             = 10y+x                                                according to the question,                                                                                                                                                           x        = 3y                        ------(1)                                                             (10x+y)+(10y+x)    = 88                                                                                        11x+11y                         =88                                                                                                                     x+y    =8                         ------(2)                       (1)in(2)=>      3y+y          =  8                                                                                                                    4y      =   8                                                                                                                          y  =8/4=2                                                                                                     so     x           = 3y = 3*2 =6                                                                    so original number = 10x + y = 10*6+2 =60+2=62
