Given:-
- Rekha had Rs. 65. She bought some notebooks. The cost of each notebook is Rs 4⅓.
To Find:-
- How many notebooks did she buy?
Solution:-
- Let the no. of notebooks of Rs 65. be x.
According to the question.
1 : 4⅓ = x : 65
1 : 13/3 = x : 65
1/(13/3) = x/65
3/13 = x/65
3(65) = x(13)
195 = 13x
195/13 = x
15 = x
x = 15
Hence, She bought 15 notebooks of Rs 65.
