STEP-BY-STEP
Let the number of tickets sold in first week be x
So acc. to the question tickets sold in second week= 120x/100
In third week= 116/100* 120x/100
In fourth week= 80/100* 116/100* 120x/100 = 1392 (Acc. to the question) ..... (i)
Solving (i) for x we get x= 1250
So acc. to the question tickets sold in second week= 120x/100
In third week= 116/100* 120x/100
In fourth week= 80/100* 116/100* 120x/100 = 1392 (Acc. to the question) ..... (i)
Solving (i) for x we get x= 1250
