The table given below shows the cost price and value of profit of 6 articles.

J1 = The value of average cost price of A, B , C and D.

J2 = The total profit of all articles.

What is the value of (L1 : J2)?

3 : 7

J1 = The value of average cost price of A, B , C and D.

= \(\frac{300 + 250 + 150 + 200}{4}\)

= \(\frac{900}{4}\)

= 225

J2 = The total profit of all articles.

= 50 + 25 + 100 + 150 + 75 + 125

= 525

Now ,  L1  :   L2 = 225 :  525

                            3    :    7
