Question

An orchestra having 6 musicians can play a piece of music in 7 minutes and 15 seconds. How much time they will take to play the same music, if the number of musicians in the orchestra is doubled?​

Answer 1

Answer:

217.5 seconds

Explanation:

Lets convert the time into seconds.

hence , 7min 15 seconds = 435 seconds

Now , 6 musicians can play a piece of music in 435 sec

1 musician will play the music in 435 * 6 sec [ Less musician , more time required]

12 musicians will play the music in 435 * 6 /12 sec [ More musicians , less time required ]

=> 217.5 seconds

Therefore , 12 musicians can play a piece of music in 217.5 seconds
