Answer 2

two box cost 1400 rs
one box cost 1400÷2
one box cost 700

first box made profit 10%
first box sp= (700×10)÷100
first box sp=70
first box sp=700+70=770

second box 10% loss
second box sp=(700×10)÷100
second box sp=70
second box sp=700-70=630

overall = total sp = 1400
now sp= 630+770= 1400
neither profit nor loss
