Question

If the numerator of a fraction is increases by 2 and the denominator is decreased by 1.6
becomes 2/3.If the numerator is increased by 1 and denominator is increased by 2x
becomes 1/3.Find the fraction.​

Answer 1

Answer:

let the N be X

and D be y

A/Q

X+2/y -1.6 = 2/3

3x+6 = 2y -3.2

3x-2y = -2.8.........(i)

and

X+1/y+2 = 1/3

3x+3=y+2

3x-y =-1.... ......(ii)

on subtracting (i) from (ii) ,then we get

3x-y =-1

3x -2y =-2.8

- +. +

y=1.8

and X =.8/3

fraction =.4/2.7
