Question

please solve both sums and send
13 ans is 26 and 14 is 73​

Answer 1

Explanation:

let the tens digit's no. be x

so, the unit digit's no. is 3x

so, the required no. is 10*x + 1*3x

=13x

if the no. is reversed it becomes 3x * 10 + 1*x

=31x

B/P 31x = 13x + 36

or, 31x - 13x = 36

or, 18x = 36

or, x= 36/18

or, x= 2

so, x= 2

The original no. is 10*2 + 1*3*2

=20*6

=26 (ans)
