there are more than 501 students in a school such that 20% of them exactly took physics and 28% of them exactly took math. What could be the least possible no of students in the school?  Choose the correct choice from the following choices
A) 550	B) 570	C) 600	D) 700	E) none of these
20% means 1/5 and 28% means 7/25,taking the lcm of the denominators 5 and 25 we get 25,the least multiple of 25 which is greater than 501 is 525. So, answer is none   ANSWnone of theseR:none of these
