Question

lf 2+4+6=19, 3+6+9=43, 4+6+8=53 then 9+5+3=? There's a logic.

Answer 1

2+4+6=19, 3+6+9=43, 4+6+8=53 then 9+5+3=? 

For this 2+4+6=19 the logic is (2x4 + 2x6) - 1

For this 3+6+9=43 the logic is (3x6 + 3x9) - 2

For this  4+6+8=53 the logic is (4x6 + 4x8) - 3

 For this 9+5+3 the logic is (9x5 + 9x3) - 4 = 68 (Ans)

Answer 2

Nice question !!
Answer will be 68

2 + 4 + 6 = 19 ⇒ 2 × (6 + 4) - 1 = 20 - 1 = 19
3 + 6 + 9 = 43 ⇒3 × (6 + 9) - 2 = 45 - 2 = 43
4 + 6 + 8 = 53 ⇒4 × (6 + 8) - 3 =56 - 3 = 53
9 + 5 + 3 = 68 ⇒9 × (5 + 3) - 4 = 72 - 4 = 68

Hence, answer is 68 . I hope logic will be clear.
