7 is related to 9.8 following a certain logic. Following the same logic, 11 is related to 15.4. To which of the given options is 9 related, following the same logic? (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 тАУ Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
13.8
12.4
12.6
11.6
12.6
Divide the second number by the first to find the constant multiplier (9.8 / 7 = 1.4). Apply this multiplier (1.4) to the third number (9 * 1.4 = 12.6).
Divide the second number by the first to find the constant multiplier (9.8 / 7 = 1.4). Apply this multiplier (1.4) to the third number (9 * 1.4 = 12.6).
Analyze the first pair
Divide 9.8 by 7 to determine the relationship: 9.8 / 7 = 1.4. The relation is (First Number * 1.4 = Second Number).
Verify with the second pair
Check if the same logic applies to 11 and 15.4: 11 * 1.4 = 15.4. The logic is verified.
Apply to the target number
Apply the multiplier 1.4 to 9: 9 * 1.4 = 12.6.
A: 13.8 is incorrect as 91.4 does not equal 13.8. B: 12.4 is incorrect as 91.4 does not equal 12.4. D: 11.6 is incorrect as 9*1.4 does not equal 11.6.
C is correct because the mathematical relationship between the numbers is a constant multiplier of 1.4, and 9 multiplied by 1.4 equals 12.6.
In number analogy questions, always check for simple multiplication or division ratios first before exploring addition or squaring patterns.
