Select the option in which the numbers are related in the same way as are the numbers of the following set.
47 : 58 : 71
Answer & explanation
Correct answer: option 1
THE LOGIC FOLLOWED HERE IS :
STEP 1 = IST NUMBER
STEP 2 = IST NUMBER + ( DIGIT SUM OF IST NUMBER ) = IIND NUMBER
STEP 3 = IIND NUMBER + ( DIGIT SUM OF IIND NUMBER) = IIIRD NUMBER
IN
47 : 58 : 71
STEP 1 = 47
STEP 2 = 47 + ( 4 +7 ) = 58
STEP 3 = 58 + ( 5 + 8) = 71
SIMILARLY IN
72 : 81 : 90
STEP 1 = 72
STEP 2 = 72 + (7 +2 ) = 81
STEP 3 = 81 + ( 8 + 1) = 90
