Which of the following statement is correct?
I. The ratio of production of bike to the production of truck by company M are 7 : 4.
II. The difference between average of production of bike and truck by all companies is 10.
Answer & explanation
Correct answer: option 4
I. The ratio of production of bike to the production of truck by company M are 7 : 4.
Production of Bike by M : Production of truck by M
350 : 200
7 : 4
Statement I is correct .
II. The difference between average of production of bike and truck by all companies is 10.
Average production of Bike = \(\frac{600 + 350 + 400 + 150 + 200 }{5}\)
= \(\frac{ 1700 }{5}\)
= 340
Average production of Truck = \(\frac{400 + 200 + 100 + 500 + 550 }{5}\)
= \(\frac{ 1750 }{5}\)
= 350
Difference = 350 - 340 = 10
Statement II is correct.
Ans :-Both I and II
