Answer:
Given :
A man buys a few number of books at RS 72 each and a few number of pens at RS 25 each .
To Find :
If he buys 11 articles and pays RS 510 altogether,find the number of each article bought by him .
Solution:
Total no. of article = 11
Let x be the no. of books bought for RS 72 each
So, No. of pens bought for RS 25 each = 11-x
Cost of x books = 72x
Cost (11-x) pens = 25(11-x)
He buys 11 articles and pays RS 510 altogether
So,72x+25(11-x)=510
72x+275-25x=510
47x=510-275
x=5
So,No. of pens bought for RS 25 each = 11-x=11-5=6
Hence 6 pens and 5 books were bought by him.
