Two numbers are in the ratio 3 : 2. If 8 and 6 are
subtracted from the first and the second number respectively, the ratio becomes 8 : 5. The numbers are:Solution
Ratio of two numbers =3:2 Let the first number =3x and second =2x ATQ- (3x-8)/(2x-6) =8:5 15x-40=16x-48 16x-15x =48-40 X =8. First number =3x =3×8=24 Second number =2x =2×8=16.
