Jumlah 4 bilangan genap yang berurutan adalah 156. Jika Bilangan 1 adalah n, tentukan n!
A.
N=38
B.
N=26
C.
N=36
D.
N=24
Correct Answer C. N=36
Explanation The sum of four consecutive even numbers is 156. If the first number is represented by n, we need to determine n!. Since the numbers are even, we can deduce that n must also be even. By trial and error, we find that when n=36, the sum of the four consecutive even numbers is indeed 156. Therefore, the correct answer is N=36.

C.
RP.700.000,00
D.
RP.750.000,00
Correct Answer C. RP.700.000,00
Explanation The total amount earned by selling 3 TVs, 2 refrigerators, and 5 radios is RP.2.350.000,00. We are given that the price of 1 refrigerator is RP.750.000,00 and the price of 1 radio is RP.30.000,00. To find the price of 1 TV, we can subtract the total price of the refrigerators and radios from the total amount earned. RP.2.350.000,00 - (2 x RP.750.000,00 + 5 x RP.30.000,00) = RP.2.350.000,00 - RP.1.500.000,00 - RP.150.000,00 = RP.700.000,00. Therefore, the price of 1 TV is RP.700.000,00.
