soal:

A ÷ 4 = n

B × 4 = n

C + 4 = n

D – 4 = n

n + n + n + n = 100

A = ?

B = ?

C = ?

D = ?

jawaban×cara:

n+n+n+n = 100

100 ÷ 4 = 25

n = 25

1.) a ÷ 4 = n

a ÷ 4 = 25

25 × 4 = 100

A = 100

2.) B × 4 = n

b × 4 = 25

25 ÷ 4 = 6,25

B = 6,25

3.) C + 4 = n

c + 4 = 25

25 – 4 = 21

C = 21

D – 4 = n

D – 4 = 25

25 + 4 = 29

D = 29

jawaban:

A = 100

B = 6,25

C = 21

D = 29

Note : Karena N + N + N + N = 100 jika nilai N sama , maka : 100 ÷ 4N = 25

A ÷ 4 = N / 25

N x 4 = 100 Nilai A

B x 4 = N / 25

N ÷ 4 = 6,25 Nilai B

C + 4 = N / 25

N – 4 = 21 Nilai C

D – 4 = N / 25

N + 4 = 29 Nilai D
