Answer 1

Answer:

GIVEN :

A man bought 20 cows in Rs. 200000. If the average cost of 12 cows is Rs.12500, what will be the average cost of remaining cows.

TO FIND :

The average cost of remaining cows.

SOLUTION :

Given that a man bought 20 cows in Rs. 200000. And the average cost of 12 cows is Rs.12500

Let m be the total number of cows

⇒ m = 20

Let a be the cost of 1 cow

⇒ a = 10000

Let b be the cost of 12 cows

For n = 12 cows the cost  b= 12500  

If the average of m observations is 'a' and the average of n observations taken out of  is 'b', then

By using the formula

=6250

Average cost of remaining 8 cows =Rs. 6250
