Question

the cost of a square field at R's27.50 per metre is R's 55000 find the cost of reaping the field at R's45 per 100sq.m

Answer 1

I think the rate shall be ₹27.50 per square metre instead of per metre. If so then;

Solution:
Area of the square field = Total cost / Rate
= 55000 / 27.50
= 2000 m^2

Since rate of reaping the field is ₹45 per 100 m^2.
Therefore, Total cost of reaping
= (2000/100) × 45
= 20 × 45
= 900.

Hence, Total cost of reaping the square field is ₹900/-

Hope you got it!
