couldnt do it! Its a linear equation thing

ankit042 · Answer

how about this
assume his initial salary as a
and monthly increment as d
now we have two unknowns and you can create two equations

ankit042 · Answer

how?

salary is on monthly basis and increment on yearly

ankit042 · Answer

hmm but increment will be for monthly salary
so 4500 = a+3d
and 5400 = a +9d

how come?

ankit042 · Answer

let us assume fixed increment is d rs pm(per month) and and his initial salary was a rs pm.
Year                  Monthly salary
First year              a
second year          a+d
third year               a+2d
fourth year             a+3d
