In the first quarter, the profit of clothing was a yuan, and that of household appliances was more than 40000 yuan. In the second quarter, the profit of clothing decreased by 15%, while that of household appliances increased by 30%. In the second quarter, compared with the first quarter, the total profit of household appliances increased or decreased? How many yuan did it increase or decrease

In the first quarter, the profit of clothing was a yuan, and that of household appliances was 2A + 40000 yuan;
In the second quarter, the profit of clothing was 0.85a yuan,
In the second quarter, the profit of household appliances was 1.3 * (2a + 40000) = 2.6a + 52000 yuan
In the first quarter, the total profit of clothing and household appliances was 3A + 40000
In the second quarter, the total profit of clothing and household appliances was 3.45a + 52000
So: compared with the first quarter, the total profit of clothing and household appliances in the second quarter increased by (3.45a + 52000) - (3a + 40000) = 0.45a + 12000 yuan
