Select the set in which the numbers are related in the same way as are the numbers of the following set.
(18, 5, 65)
(14, 3, 61)
(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 /deleting /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)
Answer & explanation
Correct answer: option 4
Logic : [(Second No.)2 + Third No. ] ÷ 5 = First No.
( 18 , 6 , 65 ) =
1) (18, 5, 65) :[ (5)2 + 65 ]÷5 = [ 25 + 65]÷5 = 90 ÷ 5 = 18
And
2) (14, 3, 61) :[ (3)2 + 61 ]÷5 = [ 9 + 61]÷5 = 70 ÷ 5 = 14
Similarly,
( 25 ,11 ,4) = [ (11)2 + 4 ]÷5 = [ 121 +4]÷5 = 125 ÷ 5 = 25 (satisfied )
so answer is ( 25 ,11 ,4)
