उत्तर
The total cost for 18.5 m of cloth is Rs. 666. The cost per meter is:
Cost per meter `= ("Total cost")/("Length of cloth") = 666/18.5`
Perform the division:
`666/18.5=36` (Cost per meter is Rs. 36).
The cost for 3.8 m of cloth is:
Cost = Cost per meter × 3.8 = 36 × 3.8.
36 × 3.8 = 136.8.
The cost of 3.8 m of cloth is: Rs. 136.8
