correct answer is: a) ₹\;80.50

Explanation

Here, the ratio of prices of two books is 2\;:\;5\;.
And, the first book price is ₹\;32.20
Let, the second book price is ‘x’.
According to the question :
2\;:\;5=32.20\;:\;x
\rightarrow\large\frac{2}{5}\normalsize=\large\frac{32.20}{x}
\rightarrow 2x=\left(32.20\times5\right)
\rightarrow x=\large\frac{3220\times5}{2\times100} _{[remove decimal]}
\rightarrow x=80.50
So that, the second book price is ₹\;80.50
Ans: The second book price is ₹\;80.50\;.

This precise math question can be conveyed differently as well:

1. If the first book costs ₹32.20 and the price ratio of the two books is 2:5, what is the price of the second book?
2. If the price of one book is ₹32.20 and the price ratio of the two books is 2:5, what is the price of the second book?
3. With the first book priced at ₹32.20 and a price ratio of 2:5 between the two books, what is the price of the second book?
