the unit's digit. If the sum of its all three digits is 12. Find the number.
Solution. Let the number be abc i.e. 100a + 10b + c
where unit digit = c, ten's digit = b and hundred's digit = a.
Given b = 3c and a = 2c
Also a + b + c = 12
From (i) and (ii), we have
2c + 30 + c = 12 = 6C = 12 c = 2
b = 3c = 3 x 2 = 6 and a = 2c = 2 2 = 4
:. The number = 100 x 4 + 10 x 6 + 2 = 400 + 60 + 2 = 462
Hence, the required 3-digit number is 462.
