Question : Directions: Choose a similar group of numbers based on certain common properties they possess.
(72, 66, 96)
Option 1: (54, 57, 78)
Option 2: (24, 69, 58)
Option 3: (55, 66, 77)
Option 4: (63, 70, 86)
Correct Answer: (55, 66, 77)
Solution :
Given:
(72, 66, 96)→72 ÷ 12 = 6, 66 ÷ 11 = 6, 96 ÷ 16 = 6. Here, all the numbers are multiples of 6.
Let's check the options –
First option:
(54, 57, 78); 54 ÷ 9 = 6, 78 ÷ 13 = 6 and 57 ÷ 19 = 3
Second option:
(24, 69, 58); 24 ÷ 4 = 6, 69 ÷ 23 = 3 and 58 ÷ 29 = 2
Third option:
(55, 66, 77); 55 ÷ 5 = 11, 66 ÷ 6 = 11, 77 ÷ 7 = 11. Here, all the numbers are multiples of 11.
Fourth option:
(63, 70, 86); 63 ÷ 9 = 7, 70 ÷ 10 = 7, 86 ÷ 2 = 43
So, only the third option follows the same pattern as followed by the given set of numbers. Hence, the third option is correct.
