Select the option that is related to the fourth number in the same way as the first number is related to the second number and fifth number is related to sixth number.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
639 : 1921 :: ? : 2206 :: 165 : 499
Show answer & explanation
Correct answer: C
Explanation
Just as:
639 → 1921
639 × 3 = 1917
1917 + 4 = 1921
And:
165 → 499
165 × 3 = 495
495 + 4 = 499
Similarly:
? : 2206
We must reverse the process:
2206 − 4 = 2202
2202 ÷ 3 = 734
Correct Option: 734
