begin mathsize 16px style CP space of space 15 space kg space equals 10 cross times 15 rs equals 150 rs
now space 2 kg space is space lost
so space 13 space kg space is space sold space at space 12 percent sign space profit
space percent sign space profit equals fraction numerator SP minus CP over denominator CP end fraction cross times 100
12 equals fraction numerator SP minus 150 over denominator 150 end fraction cross times 100
find space SP space equals 168
So space he space sold space 13 space kg space at space 168 space rs end style
