Step-by-step explanation:

Let the hundreds digit be x

So, tens digit = 4x

Also, ones digit = 3x

TRY 1.

Let x be 1

So, the no. is 1,1×4,1×3 = 143

Sum of digits = 1+4+3 = 8

HENCE, TRY 1. IS REJECTED

TRY 2.

Let x be 2

So, the no. is 2,2×4,2×3 = 286

Sum of digits = 2+8+6 = 16

HENCE THE NO. IS 286
