P1 x M1 / L1 = P2 x M2 / L2 ...(1)
In the above formula, P1 and P2 represent number of programmers in I and II scenarios respectively ; M1 and M2 minutes required for completion of work in I and II scenarios respectively and L1 and L2 represent number of lines of code in I and II scenarios respectively.
Given values : P1 = 15, L1 = 15, M1 = 15, P2 = 84, L2 = 84. We have to find M2
Applying given values in equation 1 we get,
15 X 15 / 15 = 84 X M2 / 84
Simplifying we get, M2 = 15 minutes

poojitha  (10 years ago)

it's a chain rule problem.
15/84=15/84=x/15
gives 15 mins as answer.

ans b
by using chain rule,
84:15

15:84 ::15:x when calculating x we will get 15min
