Coded Blood Relation Problems Question 6 Detailed Solution
Download Solution PDFThe logic followed here is : (2nd number × 5) - 1st number = 3rd number
Given :
- First row : 18, 9, 27
(9 × 5) - 18 = 27
45 - 18 = 27
27 = 27 (LHS = RHS)
And,
-
Second row : 40, 36, 140
(36 × 5) - 40 = 140
180 - 40 = 140
140 = 140 (LHS = RHS)
Similarly,
- Third row : 40, 13, ?
(13 × 5) - 40 = ?
65 - 40 = ?
25 = ?
Hence, "25" is the correct answer.

Coded Blood Relation Problems Question 10 Detailed Solution
Download Solution PDFThe logic followed here is : (5 × 1st number) - (4 × 2nd number) = 3rd number
So,
- First row - 12, 7, 32
(5 × 12) - (4 × 7) = 32
60 - 28 = 32
32 = 32 (LHS = RHS)
And,
- Second row - 17, 13, 33
(5 × 17) - (4 × 13) = 33
85 - 52 = 33
33 = 33 (LHS = RHS)
Similarly,
- Third row - 14, 8, ?
(5 × 14) - (4 × 8) = ?
70 - 32 = ?
38 = ?
Hence, "38" is the correct answer.
