The table given below shows the production of bike and truck by five companies.
| Production | ||
| Companies | Bike | Truck |
| A | 300 | 200 |
| B | 175 | 100 |
| C | 200 | 50 |
| D | 75 | 250 |
| E | 100 | 275 |
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) ?
Answer & explanation
Correct answer: option 3
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
