Answer 1

Step-by-step explanation:

First Case - A multiple of 70 between 300 and 500

=> all possibilities = 350,420,490

Second Case - its 20 more than a multiple of 100

= between 300 and 500 all possibility = 300,400,500

300+20=not matched, 400+20=matched,500+20=not matched

we get the answer which is 420
