Hint: In this particular question use the concept that in one and half thousand rupees there are 1500 Rs. So the total number of ten rupee notes is the ratio of the total amount in one and a half thousand rupees to the total amount in a ten rupee note.

Now we have to find out how many 10 rupee notes can we have in one and a half thousand rupees.
As we know that the total amount in a ten rupee note is equal to 10 Rs.
So, total amount in a ten rupee note = 10 Rs.
As we know that one thousand rupees = 1000 Rs.
So one and a half thousand rupees = $\left( {1\dfrac{1}{2}} \right)1000$ Rs.
Now simplify it we have,
So one and a half thousand rupees = $\left( {\dfrac{{2 + 1}}{2}} \right)1000$ Rs.
So one and a half thousand rupees = $\left( {\dfrac{3}{2}} \right)1000 = 1500$ Rs.
So the total amount in one and a half thousand rupees = 1500 Rs.
Now the total number of ten rupee notes is the ratio of total amount in one and a half thousand rupees to the total amount in a ten rupee note.
Therefore, total number of ten rupee notes = $\dfrac{{{\text{total amount in one and a half thousand rupee}}}}{{{\text{total amount in a ten rupee note}}}}$
Now substitute the values we have,
Therefore, total number of ten rupee notes = $\dfrac{{1500}}{{10}} = 150$ Notes
So there are a total 150 ten rupee notes which makes one and a half thousand rupees.

Note: Whenever we face such types of questions the key concept we have to remember is that always recall that the total amount in a ten rupee note is Rs. 10 and always recall that in one thousand rupee there is 1000 Rs, so in a half thousand there is 500 rupees so in one and a half thousand there is 1500 Rs.
