- We're provided - price of 6 books = Rs 480 & we're asked to find out the price of 3 books.
- Firstly , find out the price of 1 book.Use the unitary method for obtaining unit quantity. For the cost of 1 book , the cost of 6 books should be divided by 6 [ i.e 480 / 6 ].
[tex] \large{ \tt{↦ \: PRICE \: OF \: 1 \: BOOK = \frac{480}{6} = \boxed{ \tt{Rs \: 80}}}}[/tex]
- Secondly , Find out the price of 3 book as we're asked above. Since the cost of 3 books is more than that of 1 book, the cost of 1 book should be multiplied by 3 [ i.e 80 × 3 ]
[tex] \large{ \tt{↦ \: PRICE \: OF \: 3 \: BOOK = 80 \times 3 = \boxed{ \boxed{ \tt{Rs \: 240}}}}}[/tex]
