Solution:

Total expenditure of labour

=\;{3000000}/{120} × 90=2250000

New labour expenditure

=\;{2250000}/{100} × 105

=2362500

Increase in expenditure on labour

=2362500-2250000=112500

Other expenditure

=\;{3000000}/{120} × 70

=1750000

Hence, expenditure on other expenses to be reduced to maintain the profit

=\;{112500}/{1750000} × 100=6.43 \%
