The digit in unit's place of a three digit number is thrice the digit in ten's place & the digit in hundred's place is two-third of the digit in ten's place. If the sum of three digits of number is 14
A). 239
B). 221
C). 215
D). 211
239
Let the ten's digit be x.
∴ Unit's digit = 3x
Hundered's digit = 2x/3
∴ x + 3x + 2x/3 = 14
= 3x + 9x + 2x = 14 x 3
= 14x = 14 x 3
= x = 3
∴ Number = 239
