We may balance the forces in order to calculate the tension.
We know that there are no horizontal forces being applied. Next, the vertical forces are:
Weight (W) which is acting downwards
Tension in each wire (T) which is acting upwards
Because the sign is stationary, the downward force must equal the upward force. So we may write:
Weight = 4 * tension
W = 4T
100 = 4T
T = 25 N
The tension in each wire is 25 Newtons

Answer:
d) 1000 times
Explanation:
As we know that difference of sound level is given as
so here we need to find the ratio of two intensity
it is given as
now we have
so it is
d) 1000 times
