those who do this question i will mark us as a brilliant

loss=10%

sp with vat=rs25425

sp=sp with vat-vat%of sp=rs25425-13/100×sp

sp+13/100×sp=rs25425

(100sp+13sp)/100=rs25425

113sp=rs2542500

sp=rs2542500/113=22500

cp=sp+loss %of cp

cp-10/100×cp=22500

(10cp-cp)/100=22500

9cp=2250000

cp=2250000/9=250000
