Answer 2

lets check the answer by trial and error method

the multiples of 120 are

120,240,360,480,600,720,840,960,1080,1200 etc.

the number 120 doesn't lie between 400 and 500

the number 240 doesn't lie between 400 and 500

the number 360 doesn't lie between 400 and 500

the number 480 lie between 400 and 500 and the digit at hundred place is half of the digit at tens place

so 480 is the answer
