Question

The sum of the digits of a two digit number is 10 and the digit at unit place is two third of the digit at tens place find the number​

Answer 1

let the digit at tens place= x

then, digit of unit place=2/3*x

now, according to question

x+2/3*x = 10

5x/3 = 10

5x = 3×10.

x = 30/5

x= 6

hence, digit at unit place = 2/3*x

=2/3*6

= 4

digit of tens place= x=6.

then, the whole number=46.
