In a race of length L metres, Johnson beats Lewis by M metres and Greene by N metres, By how many metres does Lewis beat Greene in the same race ? (M<N)
Choose the correct choice from the following:
A) L(L-N) / L-M B) M+ C) L-N D) M-N E) L(N-M)/ L-M
For my work, i took the following numbers:   L = 100   M = 10   N =20.   So basically, L beat G by 10 meters. Now whatever options comes close to the figure 10 is the right ans..   looking the the opion C to E, one can make out that they are incorrect, leaving us with just two options..A and B.   Out of which, i choose L(N-M)/ L-M.
