Answer Posted / shanoor
first consider 1/4 means out of 4hrs he uses 1hr for flow
chart,4*12=48 .out of 4hrs we take 1hr only 1*12=12.so he
takes 12hrs out 48 hrs for flow chart.next he spends 3/8
means 8*6=48.out 8hrs spends 3hrs for the coding so
3*6=18.by this 18hrs spends for the coding .total he spends
12+18=30 hrs out 48hrs .only 18 for the debugging .
