Question

A cow yields $10\frac{7}{10}$ litres of milk everyday.Find how many litres of the milk is the yield by the cow in a week?

Answer 1

Milk yields by the cow in a day $=10\frac{7}{10}=\frac{10x10+7}{10}=\frac{107}{10}litres$

So in two days it will be $=\frac{107}{10}+\frac{107}{10}=\frac{214}{10}\left(2x\frac{107}{10}=\frac{214}{10}\right)$

similarly ,

Milk yields by cow in a week $=7x\frac{107}{10}$ As there are Seven days in a week.

$$\begin{gathered} =\frac{7x107}{10} \\ =\frac{749}{10} \\ =74\frac{9}{10}litres \end{gathered}$$

Hence milk yields by the cow in a week is $74\frac{9}{10}litres$
