Answer:

Here is the solution mark as brainliest please

Step-by-step explanation:

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.
