Answer 1

Explanation:

Total money spend by seller =75×30=Rs.2250

he sold 1/3 apples at a loss of 5%

if he sold 1/3 apples =25kg apples at a rate Rs.30 then =25×30=Rs.750

100

5

=37.5

but he wanted 10% gain at total amount =2250×10%=Rs.225

Let he sold his rest apples at a rate x then

50×x=37.5+225+1500(50×=1500)

x=

50

225+1500+37.5

−35.25Rs
