Answer 2

The number is 64

Given data :

Sum of two digits = 10

Unit's digit = 2/3 × Ten's digit

Let,

The ten's digit = x

And, unit's digit = 2/3 × x = 2x/3

So,

x + 2x/3 = 10

(3x+2x)/3 = 10

5x/3 = 10

x = (10×3)/5

x = 30/5

x = 6

So, Ten's digit = 6

Unit's digit = (6× 2/3) = 4

So,the number = 64 (Answer)
