Solution
The correct option is D
A + B + C + D + E = 2012 (A>11, B>21, C>30, D>40, E>50)
This is a lower limit Similar->Different question.
So, we assign the minimum values that can be taken by each of A, B, C, D and E and reframe the equation:
A + B + C + D + E = 1855 (Assigning 12 to A, 22 to B, 31 to C, 41 to D and 51 to E)
Using the 1-0 method: Required Answer = 1859C4.Option (d)
A + B + C + D + E = 2012 (A>11, B>21, C>30, D>40, E>50)
