Always assume total work is 1 4 worker complete work in 42 days So 1 workers 1 day work is 1/(42*4)=1/168 12(n1) days works for 4 workers is = 4*(1/168)*12 ==> 12/42 ==> 2/7 Balance work = 1-(2/7)= 5/7 1 worker left after 12 days So now we have only 3 workers and 3 workers one day job is 3*(1/168)= ...

Total work = 1
So Balance work is = 1-(5/6) =1/6 So B's 3 hour work is 1/6 and 1 hour work is 1/3*6 = 1/18
Total work = 1 so n = 18

*Both the scheme pay equal interests*(important data) So S.I = C.I Assume that Amount invested by "B" is "x" So A = 6100-x B = X S.I = PNR/100 = X(4)(10)/100 THIS IS FOR (B) C.I = P[(1-R/100)^n-1] = (6100-X)[(1-1/100)^2 = 21(6100-X)/100 X(4)(10)/100 = 21(6100-X)/100 40X = 128100-...
