Jawaban:

A. Jendela

J = 1

e = 2

n = 1

d = 1

l = 1

a = 1

Total huruf = 7!

unsur ganda = 2(e)

7! =

= 7 × 6 × 5 × 4 × 3 × 2 × 1

= 42 × 5 × 4 × 3 × 2 × 1

= 210 × 4 × 3 × 2 × 1

= 840 × 3 × 2 × 1

= 2.520 × 2 × 1

= 5.040 × 1

= 5.040

Opsi A. Tidak tepat

B. Sedap

S = 1

e = 1

d = 1

a = 1

p = 1

Total huruf = 5!

Unsur ganda = -

5! =

= 5 × 4 × 3 × 2 × 1

= 20 × 3 × 2 × 1

= 60 × 2 × 1

= 120 × 1

= 120 susunan

Opsi B. tidak tepat

C. mie

m = 1

i = 1

e = 1

total huruf = 3!

Unsur ganda = -

3! =

= 3 × 2 × 1

= 6 × 1

= 6 susunan

D. unsur

u = 2

n = 1

s = 1

r = 1

total huruf = 5!

Unsur ganda = 2(u)

5! =

= 5 × 4 × 3 × 2 × 1

= 20 × 3 × 2 × 1

= 60 × 2 × 1

= 120 × 1

= 120 susunan

Opsi D. tidak tepat

E. enak

e = 1

n = 1

a = 1

k = 1

total huruf = 4!

Unsur ganda = -

4! =

= 4 × 3 × 2 × 1

= 12 × 2 × 1

= 24 × 1

= 24 susunan

Opsi E. Enak ( tepat ) karena memiliki 24 susunan
