• A. ₹ 595
• B. ₹ 700
• C. ₹ 720
• D. ₹ 5040

Answer 1

Answer: (A), (B), (D)

The correct options are
A ₹ 595
B ₹ 700
D ₹ 5040

Money earned per day $=₹85$

In a week, there are 7 days.
So, the money earned in a week is $₹85\times 7$, which can be written as $(80+5)\times 7$.

$\begin{array}{ccc}& 80& 5\\ 7& 7\times 80& 7\times 5\\ & =560& =35\end{array}$

$85\times 7=(80\times 7)+(5\times 7)=560+35=595$

So, Sana earns ₹ 595 per week.
