A giri reads 5 hours daily to complete 3 books in 21 days. In how many days will she complete 6 books reading 7 hours daily

Answer 1

Answer:

Girl can complete 6 books reading 7 hours daily for 30 days

Step-by-step explanation:

Given that a girl reads 5 hours daily to complete 3 books in 21 days

Time taken to complete reading of 3 books $=\hspace{0.1cm}(\,21 \times 5)\,\hspace{0.1cm}=\hspace{0.1cm}105\hspace{0.1cm}hours$

Time take to complete reading of 1 book $=\hspace{0.1cm}\frac{105}{3}\hspace{0.1cm}=\hspace{0.1cm}35\hspace{0.1cm}hours$

Now, girl complete 6 books reading 7 hours daily.

Time taken to complete reading of 6 books $=(\,6 \times 35)\,\hspace{0.1cm}=\hspace{0.1cm}210\hspace{0.1cm}hours$

Number of days needed $=\hspace{0.1cm}\frac{210}{7}\hspace{0.1cm}=\hspace{0.1cm}30\hspace{0.1cm}days$

Hence, girl can complete 6 books reading 7 hours daily for 30 days
