The sum of the known numbers is 6999 + 8888 + 777 = 16664. To find the missing number, subtract this sum from 19700: 19700 - 16664 = 3036. However, the options given (36, 16, 64, 26) do not include 3036. The question as stated is inconsistent with the options. The search results show a similar question but with 9999 instead of 6999, where the missing number is 36. Assuming the intended question was 9999 + 8888 + 777 + ? = 19700, the missing number is 36, which corresponds to option A. Therefore, the question and options should be corrected to use 9999 instead of 6999, making the correct answer A (36).

Revenue is calculated as Price × Quantity. When the price of TV sets is increased by 30%, the new price becomes 1.3 times the original price. When sales decrease by 20%, the quantity sold becomes 0.8 times the original quantity. Therefore, the new revenue is 1.3 × 0.8 = 1.04 times the original revenue, which means revenue increases by 4%. Hence, the effect on the revenue receipts of the shop is a 4% increase.

Total votes = 7500; invalid votes = 20% of 7500 = 1500; valid votes = 7500 - 1500 = 6000. One candidate got 55% of valid votes = 0.55 × 6000 = 3300. The other candidate got the remaining valid votes = 6000 - 3300 = 2700. However, 2700 is option A, but the question asks for the number of valid votes the other candidate got, which is 2700. The original correct_answer was A, which matches 2700, so the original answer is correct. The explanation was missing and is now provided. The difficulty is set to easy as it involves basic percentage calculations.

The correct contraction for 'let us' in imperative sentences is "Let's." Therefore, "Let's get out of here" is the grammatically correct phrase. The other options are incorrect because "Let get" lacks the pronoun, "Let's us get" is redundant, and "Let's to get" is ungrammatical.

If the price increases by 20%, the new price is 120% of the original. To keep expenditure the same, consumption must be reduced to 100/120 = 5/6 of original, which is a reduction of (1 - 5/6) × 100% = 16.66%.
