1.let the CP of two cows be x and y.Now acc to given statements---(x+10x/100) + (y-10y/100) = 210[10%profit as 10/100 of CP of first cow and like wise for other]also,total profit is 5%,hence (x+y)+5/100(x+y) = 210solving both equations---Cost Price of cows is Rs.100 each.3.let the no. of female clerks be F.Let no. of male clerks be M.according to given stat---2F+M=30F+3M=30solving both equations---M=6,F=124.i guess answer is Monday.As the day after tommorow is Sunday.The day before sunday is saturday.And said is 2 days after this day(saturday)---So ans is Monday.
