Directions: Study the following pie-chart carefully to answer the questions given below.
Total number of passengers in six different planes are 1800.
Percentage of passengers in six different planes A, B, C, D, E and F in pie-chart given below.
What is the average number of passengers travelling in Plane-B, Plane-E and Plane-F together?
280
300
340
360
Answer: (d) 360Solution: Total percentsge of passengers in all three planes are 60%, then average number of passengers in Plane-A, Plane-B and Plane-C together, $$ = \frac{1800 \times 60}{100 \times 3} $$ $$ = 360 \ Passengers $$
If cost of one ticket is Rs.1200, then find the total amount paid by the passengers of Plane-A?
280,000
312,000
324,000
332,000
Answer: (c) 324,000Solution: Number of passengers in Plane-A, $$ = \frac{1800 \times 15}{100} $$ $$ = 270 $$ The total amount paid by the passengers of Plane-A, $$ = 270 \times 1200 $$ $$ = 324,000 \ Rs. $$
Number of passengers in Plane-A is approximately what percentage of the total number of passengers in Plane-C and Plane-D together?
What is the difference between the number of passengers in Plane-F and Plane-E?
122
108
100
96
Answer: (b) 108Solution: Difference between the number of passengers in Plane-F and Plane-E, $$ = \frac{1800 \times 6}{100} $$ $$ = 108 \ Passengers $$
