Question

Select the option in which the two numbers share the same relationship as that shared by the given number - pair. (11, 143)
1. (18, 93)
2. (17, 323)
3. (24, 216)
4. (5, 39)

Answer 1

Correct Answer - Option 2 : (17, 323)

The logic followed here is:-

Second Number = First number × (First number + 2)

The given number pair is (11, 143)

First Number = 11

Second Number = First number × (First number + 2)

= 11 × (11 + 2)

= 11 × 13

= 143 = 143

Checking the options:

1) (18, 93)

Second Number = First number × (First number + 2)

= 18 × (18 + 2)

= 18 × 20

= 360 ≠ 93

2) (17, 323)

Second Number = First number × (First number + 2)

= 17 × (17 + 2)

= 17 × 19

= 323 = 323

3) (24, 216)

Second Number = First number × (First number + 2)

= 24 × (24 +2)

= 24 × 26

= 624 ≠ 216

4) (5, 39)

Second Number = First number × (First number + 2)

= 5 × (5 + 2)

= 5 × 7

= 35 ≠ 39

Hence, the correct answer is "(17, 323)".
