answer below
Answer: 4/15
Step-by-step explanation: Total Cars to be produced in three Shifts = 210
Fraction of total cars to be produced in First Shift = 2/5
Fraction of total cars to be produced in second Shift = 1/3
Summation of all the fractions of total cars to be produced in all the three shifts should be equal to 1
Hence, fraction of total cars to be produced in third Shift = 1- (2/5) - (1/3)
= ( 15 - 6 - 5)/15 ( taking LCM of 5&3)
= 4/15

Answer:
6
Step-by-step explanation:
total no. of seats = 22 x 4 = 88
total no. of seats occupied = 19 * 4 + (22-19)*4/2 = 76 + 6 = 82
no. of empty seats = 88 -82 = 6
