30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
then 4 plus 3 equals 28 and 3 plus 3 equals 18 and 7 plus 5 equals 84 .... its easy you just have to multiply the answer with the first number.. for example : 2 plus 3 equals 5 but when you multiply the answer with the first number (2) it becomes equals 10, and so on the others..
