Question

We add 1 to numerator and subtract 1 from the denominator a fraction becomes 1 . it also becomes 1/2 if we add 1 to the denominator , then the sum of the numerator and the denominator of the fraction is?

Answer 1

let the numerator =x
and denominator =y
according to question


$x + 1 \div y - 1 = 1 \\ x - y = - 2......(i) \\ x \div y + 1 = 1 \div 2 \\ 2x - y = 1 \ .........(ii) \\ subtracting \:(i) \: from \: (ii) \\ we \: get \: 2x - x - y + y = 1 + 2 \\ - - > x = 3 \\ from(i) \\ y = 5 \\ according \: to \: question \: x + y = 5 + 3 = 8$
