Download Solution PDFGiven:
(121, 81, 2)
(88, 54, 2)
Logic: Third no. = [(First no. ÷ 11) - (Second no. ÷ 9)]
(121, 81, 2) →
⇒ [(121 ÷ 11) - (81 ÷ 9)]
⇒ (11 - 9) = 2
(88, 54, 2) →
⇒ [(88 ÷ 11) - (54 ÷ 9)]
⇒ (8 - 6) = 2
Checking all the given options:
1. (13, 5, 9)
⇒ [(13 ÷ 11) - (5 ÷ 9)]
⇒ (1.18 - 0.55) = 0.625
2. (78, 6, 45)
⇒ [(78 ÷ 11) - (6 ÷ 9)]
⇒ (7.09 - 0.66) = 6.394
3. (31, 56, 98)
⇒ [(31 ÷ 11) - (56 ÷ 9)]
⇒ (2.81 - 6.22) = (-3.41)
4. (77, 18, 5)
⇒ [(77 ÷ 11) - (18 ÷ 9)]
⇒ (7 - 2) = 5
Here, (77, 18, 5) shows a similar relation to the given set of numbers.
Hence, the correct answer is "Option (4)".
