Select the option that is related to fourth number in
the same way as the first number is related to the second number and the fifth number is related to the sixth number. 24 : 581 :: ? : 1374 :: 28 : 789Solution
The logic followed here is as follows: 5 is added to the square of the first number to get the second number. 24² + 5 = 576 + 5 = 581 Similarly, 5 is added to the square of the fifth number to get the sixth number. 28² + 5 = 784 + 5 = 789 So, Third number² + 5 = Fourth number Third number² = 1374 – 5 Third number² = 1369 Third number= 37
