Answers
The cost of the new job was Rs. 331.25
A 10.42% increase was noted in the cost of the new job
Step-by-step explanation:
The original material cost = Rs. 175
The original labor cost = Rs. 125
The original cost of the Job = Material costs + Labor costs
= 175 + 125
= Rs. 300
A 12.5% increase was seen in the material costs.
The new material cost = 175 + 12.5% of 175
= 175 + 21.875
= 196.875
A 7.5% increase was noted in the labor costs
The new labor cost = 125 + 7.5% of 125
= 125 + 9.375
= 134.375
The new cost of the job = New material cost + new labor cost
= 196.875 + 134.375
= 331.25
The cost of the new job was Rs. 331.25
The difference in the costs of the new and original job = 331.25 – 300
= 31.25
The percent increase in the cost of the new job = (31.25 / 300) x 100
= 10.42 %
Thus, the cost of the new job was Rs. 331.25
A 10.42% increase was noted in the cost of the new job
