$2: 5$
$3: 5$
$3: 2$
$2: 3$

Solution:

Concept:

A ratio compares two quantities after finding the missing share.

Explanation:

Total oranges shared

= 20

.

Ama's share

= 12

.

So, Araba's share

= 20 - 12 = 8

.

Required ratio is Araba : Ama

= 8 : 12

.

Divide both terms by

4

, the HCF of

8

and

12

.

8 \div 4 = 2

and

12 \div 4 = 3

.

Hence, Araba : Ama

= 2 : 3

.

Answer:

D.

2 : 3
