1/8 = 0.125
New wage = (1 + 0.125)
= 1.125 of the old wage
1/20 = 0.05
New length of working day
= (1 + 0.05)
= 1.05 of the length of the old working day.
The cost of digging the pit will increase by = 1.125 + 1.05 = 2.175
New cost = 2.175 x 1347
= Rs. 2929.73
New wage = (1 + 0.125)
= 1.125 of the old wage
1/20 = 0.05
New length of working day
= (1 + 0.05)
= 1.05 of the length of the old working day.
The cost of digging the pit will increase by = 1.125 + 1.05 = 2.175
New cost = 2.175 x 1347
= Rs. 2929.73
