Answers
Given : in every 5 mins 10 cannons fire 3 cannon balls to hit 270 targets in 1(1/2) hr
To Find : how many targets can be hit in 1 hour by 25 cannons firing 5 cannonballs in every 6 mins
Solution:
every 5 mins 10 cannons fire 3 cannon balls
=> every 5 mins cannon balls = 10 x 3
=> every 5 mins cannon balls = 30
=> every 1 mins cannon balls = 30/5
=> every 1 mins cannon balls = 6
1(1/2) hr = 90 mins
=> every 90 mins cannon balls = 90 x 6 = 540 cannon balls
Target Hots = 270
Ratio of target hit = 270/540 = 1/2
25 cannons firing 5 cannonballs in every 6 mins
every 6 mins 25 cannons fire 5 cannon balls
=> every 6 mins cannon balls =25 x 5
=> every 6 mins cannon balls = 125
=> every 1 mins cannon balls = 125/6
=> every 60 mins cannon balls = 60 x 125/6
=> every 60 mins cannon balls = 1250
Ratio of target hit = 1/2
=> Target Hits = 1250/2
= 625
