Solution
First, let's find out the total cost of one set of articles in the ratio 3:2:3.
The cost of one article of type P is Rs.300, so the cost of 3 articles of type P is 3*300 = Rs.900.
The cost of one article of type Q is Rs.180, so the cost of 2 articles of type Q is 2*180 = Rs.360.
The cost of one article of type R is Rs.120, so the cost of 3 articles of type R is 3*120 = Rs.360.
So, the total cost of one set of articles in the ratio 3:2:3 is 900+360+360 = Rs.1620.
Now, let's find out how many sets of articles Suresh bought. He spent Rs.6480, so he bought 6480/1620 = 4 sets of articles.
Since each set contains 2 articles of type Q, Suresh bought 4*2 = 8 articles of type Q.
