Question

The cost of 19 note books is Rs.308$\frac{3}{4}$. Find the cost of each notebook. How many note books can be bought for Rs.455?

Answer 1

The cost of 19 note books is Rs 308$\frac{3}{4}$
=Rs $\frac{1235}{4}$.
The cost of each note book=Rs$\frac{1235}{4}$
=Rs $\frac{1235}{4}\times$$\frac{1}{19}$
=Rs $\frac{65}{4}$
=Rs 16$\frac{1}{4}$.
Hence, the number of note books that can be brought for Rs $455=\frac{455}{\frac{65}{4}}$=$\frac{455\times 4}{65}$$=28$.
So, 28 note books can be bought for Rs 455.
