a) 62​

Answer 1

11. let the digit at one 's place =x

then the digit at ten 's place = 3*x

then original no. will be= 10*(3x)+x

=31x

by reversing the no.

one 's digit will be =3x

ten 's digit will be= x

then no. will be =10*x+3x

=13x

then according to the problem

10x+3x+x+30x=88

x=2

then original no will be 31*2=62
