Question

The cost of fencing a square field at 60 paise per metre is Rs. 1200.Find the cost of reaping the field at the rate of 50 paise per 100 sq metres.

Answer 1

Solution:-
Total cost of fencing a square field = Rs. 1200
Cost per meter = Rs. 0.6 
So, perimeter of the field = 1200/0.6 = 2000 m
Each side of square field = 2000/4 = 500 m
Area of the square field = 500*500
= 250000 sq m
Now, cost of repairing = Rs. 0.5 per 100 sq m
Total cost of repairing = (250000*0.5)/100
= Rs. 1250
