First, let's convert the dimensions of the table top into centimeters, since the rate given is in paise per square centimeter:
Length of the table top = 9 dm * 10 cm/dm + 5 cm = 90 cm + 5 cm = 95 cm Breadth of the table top = 6 dm * 10 cm/dm + 5 cm = 60 cm + 5 cm = 65 cm
Now, let's calculate the area of the table top:
Area of the table top = Length × Breadth = 95 cm × 65 cm = 6175 cm²
Now, let's find the cost to polish the table top at the rate of 20 paise per square centimeter:
Cost = Area of the table top × Rate = 6175 cm² × 20 paise/cm² = 123500 paise
Since 100 paise = 1 rupee, we divide by 100 to convert paise to rupees:
Cost = 123500 paise / 100 = Rs. 1235
So, the cost to polish the table top will be Rs. 1235.
