Question

the ones digit of a 2 digit no. is 3. sum of digits is 1/7 of the no. find the other digit​

Answer 1

Answer:

Step-by-step explanation:

the unit digit is = 3

let the ten's digit is = x

number thus obtained = 10x + 3

sum of the digits = x + 3

now,

x + 3 = (1/7)(10x + 3)

7x + 21 = 10x + 3

3x = 18

x = 6

therefore other digit is 6

and the number is 63
