answer is 28
proof
9=10.........
then 8=18 .....means 9-1 = 10 +8
7=24.......................8-1=18+6
6=28...........7-1=24+4
5=30................6-1= 28+2
4=30.........5-1=30-0
3=28.........3-1= 30 -2
can i ask a question?
yes bro u can
can you please explain your calculation again please like more elaborated
lol...ok
so its a logical question............so maybe it has any pattern and relationship in each equation
so its following a pattern ..........
on left hand side , it's decreasing by 1 and one right hand side its increasing by reduced form of first number by 2
ex. 9=10
now LHS - 1 = RHS + reduced for of 10 by 2
8 = 10+8
8 = 18
and thus going ............
The answer is:
X * (10 - X) + (10 - X) = Y
So, 9:
9 * 1 + 1 = 10
8 * 2 + 2 = 18
7 * 3 + 3 = 24
6 * 4 + 4 = 28
5 * 5 + 5 = 30
3 * 7 + 7 = 28
It Was interesting - not easy, not hard.
