A tech distributor purchased and supplied a batch of laptops, tablets, and smartphones to corporate clients. The cost price of each smartphone is Rs 440 less than that of each laptop. For all three gadgets, the marked price was set at a% above their respective cost prices. The entire lot of smartphones was sold collectively for Rs 1,60,000, and on each unit, a flat discount of Rs b was given off the marked price. The number of laptops supplied was 24 less than the number of smartphones, and the ratio of laptops to tablets sold was 16:5. The selling price of one smartphone and one laptop were in the ratio 4:7, respectively. For tablets, the flat discount (in Rs) and the profit (in Rs) earned on each tablet were equal. Furthermore, the selling price of each tablet was fixed at Rs 3000, which happened to be Rs 1600 more than the selling price of a laptop. The total cost price of all tablets together was found to be Rs 1,32,000. The average of the marked prices of one laptop and one tablet came out to be exactly Rs. 2610. If the marked price of 1/5th of the tablets is equal to the cost price of a laptop, another 20 tablets are marked at the cost price of a tablet, and the remaining tablets are marked at a price which is Rs. 320 more than the cost price of a smartphone, then what is the decrease in the total marked price of all the tablets?
