(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(21, 225, 9)
(12, 49, 2)
Answer & explanation
Correct answer: option 1
(21, 225, 9)
(12, 49, 2)
THE LOGIC FOLLOWED HERE IS :
[( IST NUMBER +IIIRD NUMBER ) ÷ 2 ] 2 = IIND NUMBER
AS
[( 21 + 9 ) ÷2 ] 2 = IIND NUMBER
[ 30 ÷ 2 ]2 = IIND NUMBER
[ 15]2 = IIND NUMBER
225 = IIND NUMBER
AND
[( 12 + 2 ) ÷ 2 ] 2 = IIND NUMBER
[ 14 ÷ 2 ]2 = IIND NUMBER
[ 7]2 = IIND NUMBER
49 = IIND NUMBER
SIMILARLY
(14, 64, 2)
[( 14 + 2 ) ÷ 2 ] 2 = IIND NUMBER
[ 16 ÷ 2 ]2 = IIND NUMBER
[ 8 ]2 = IIND NUMBER
64 = IIND NUMBER
