Here, we'll count the quantity of each denomination's notes as being 2, 3, and 5 accordingly. Considering that she has been handed Rs. 400000 in total, We can utilize this information to attempt and create an equation in k, which we can then solve to determine the value of k.
A ratio shows the amount of times one number is present in another. Any form of quantity, such as an object count or a measurement of length, weight, or time, can be used as one of the numbers in a ratio. If both constituent numbers are provided, the ratio can be given as " a to

" or "

" or by giving just the value of their quotient

.
