Question

Mr. Raghu returns home on a hot summer day and wants to have buttermilk. Mrs. Raghu has only curds. What can she do to get buttermilk?
Explain?

Answer 1

On a hot day, if Mr. Raghu wants buttermilk and Mrs. Raghu has only curd at home, she should add some water in the curd and churn it to separate the fat and filter the solution to have the fat mixed water or buttermilk and get the curd as the residual substance.

 Mrs. Raghu should also be using a fine cotton cloth that will act similarly as a filter paper.
