Let consider the numbers between 100 to 199;
The numbers which are divisible by 2 and 7 are 112, 126, 140, 154, 168, 182 and 196.
Total 7 numbers.
Similarly, between 200 to 299, 300 to 399, 400 to 499, 500 to 599, 600 to 699, 800 to 899 and 900 to 999; have 7 such numbers. And between 700 and 799 8 numbers including 700.
So there are (8 x 7) + 8 = 64 numbers
