Question

I am a 3 digit number.My hundred digit is the name as my onces digit. My tens digit is a multiple of 3 but not a multiple by 2. If you multiply me by 4, the estimated product is 1600.WHAT NUMBER AM I

Answer 1

Answer:

1600 / 4 = 400 ( estimated product )

Now here , even as a estimated product , the hundred digit shouldn’t change.

And as hundred digit = onces digit

the no. = 4 x 4 ( x is unknown )

x is multiple of 3 not of 2

Now , 6 is a multiple of 2 but 3 & 9 are not .

If no. is 494 , it‘S estimation will be 454 not 400.

HENCE , NUMBER = 434
