It is given that, 250 tickets of Rs 400 were sold,
Therefore, total amount received by selling these tickets = 250 x 400= Rs 100000
Similarly, amount received by selling 500 tickets of Rs 100 = 500 x 100= Rs 50000
It is also given that, 40% and 20% of entertainment tax is on Rs 400 and Rs 100 tickets, respectively.
So, total entertainment tax collected
= 40% of total amount received by selling tickets of ₹400 + 20% of total amount received by selling tickets of ₹100
= 40% of 100000 + 20% of 50000
= 40/100 x 100000 + 20/100 x 50000
= 40000 + 10000
= ₹ 50000
Hence, the total collected entertainment tax was ₹50000.
