If the first 200 numbers are written down and those divisible by 2 are deleted and again those divisible by 5 are deleted, how many numbers are left out ?  Choose the correct choice from the following:	A) 80	B) 150	C) 200	D) 160	E) None
Total numbers divisible by 2 = 100   Total numbers divisible by 5 = 40   But there is double counting. So we have to subtract Total numbers which are divisible by both 2 and 5 i.e, 200 / 10 = 20   So Total numbers which are divisible by either 2 or 5 is  100 + 40 - 20=

<output>120</output>
120   Number of numbers which are not divisible by any of those= 200 - 120= 
<gadget id="calculator">200 - 120</gadget>
<output>80</output>
80   Correct Option: 80
<result>A</result>
