answer 27
dont try such qns mathematically...
u can use logic
mehersangram100:
okay
let the no. be 10x+y
10x+y+45=10y+x
xy=14
now u can easily solve
put y=14/x
answer my question
what is quasi probability
It is object that relaxes some of kolomogorov's axioms of probability theory
need some examples

Let no be in form xy
x * y = 14
45+10x +y = 10y + x
Upon Solving,
9y - 9x = 45
y - x = 5
y = x + 5
x(x + 5) = 14
x² + 5x - 14 = 0
Factorize
(x + 7)(x - 2) = 0
x + 7 = 0
x = -7
x - 2 =0
x = 2
So x has two values -7 and 2
And y has two values -2 and 7 respectively.
No would be 27
nice
