for them to fire at same time we have to consider their LCM
Given:3,5,7
LCM(3,5,7)=105.

Divide 3600 by 105
consider only integer point and neglect decimal point as number of terms can't be decimal.
(for eg: if it is 2.78 take it as 2)

In this case 3600/105=34.28
answer is 34.

girish21shan: answer given 32
fnahm3d: [3570=105+(n-1)105 ]considering it as AP and solving yeilds same result as well may be there is some misprinting as it can be the only way
girish21shan: may be
