Show answer & explanation

Correct answer: D

Explanation

 The correct answer is option 4 i.e. 62000

Application

Total number of cars of type C1 manufactured by the given 5 companies

= 300000 × 1/3 × 2/10 + 280000 × 3/4 × 1/3  + 320000 × 1/2 × 2/4 + 400000 × 3/4 × 2/6 + 480000 × 1/3 × 1/4

= 20000 + 70000 + 80000 + 100000 + 40000

= 310000

Hence,

Average = 310000/5 = 62000
