1) Let the value of the scooter before 1 year be Rs.x

Then according to question =x−

100

15

×x=31025

=85x=3102500

=x=Rs.36500

So, the value of the scooter before 1 year =Rs.36500

2) Let the initial price be Rs.100

Then as price is reduced by 10%

Therefore new price =100−10% of100

=Rs.90

Now the difference in prices =Rs.10

Therefore,Percentage increase =

10

×100

=11.11% (approx)
