Question

In a three digit no. the tens place is thrice the units place and the hundreds digit is four times the units digit. Also the sum of its digits is 16 . find the no.

Answer 1

Let us take the units digit as 'x'

Then,

The equation goes like this -

4x+3x+x = 16

or, 8x = 16

or, x = 16/8

or, x = 2

Therefore,

If x = 2, then 3x = 2*3 =6, and 4x = 4*2 = 8. 

Therefore,

ANSWER = 862
