The table given below shows the production of bike and truck by five companies.

J1 = The average production of bike by all the 5 companies.

J2 = the average production of truck by all the 5 companies.

What is the value of (J1 : J2) ?

34 : 35

J1 = The average production of bike by all the 5 companies.

= \(\frac{300 + 175 + 200 + 75 + 100}{5}\)

= \(\frac{850}{5}\)

= 170

J2 = the average production of truck by all the 5 companies.

= \(\frac{200 + 100 + 50 + 250 + 275}{5}\)

= \(\frac{ 875 }{5}\)

= 175

Now ,  J1  :  J2  = 170  :   175

                            34  :    35
