The ages of sunitha and raseeda are in ratio of 7: 8 ten years from now there ages will be 9: 10 find there present age

Step-by-step explanation:

Both numbers of the ratio units used to express the ratio in ten years are 2 higher than at present. Thus, each ratio unit must stand for 5 years. That would make their current ages ...

  Sunitha: 7·5 = 35

  Raseeda: 8·5 = 40

If you can't figure the answer right away from the change in ratio units, then you may need to write a couple of equations:

These can be translated to standard form, which may make some methods of solution easier:

These have solution (r, s) = (40, 35).

maya’s expression will generate the wrong sum because she violated the commutative property.
