Question

2. A fruit-seller buys oranges at 4 for 3
and sells them at 3 for 4. Find his profit
percent.​

Answer 1

c.p. of 4 oranges = 3 rs

c.p. of one orange = 3/4 rs

s.p. of 3 orange = 4 rs

s.p. of one orange = 4/3 rs

profit % = (s.p. - c.p. )/ c.p. ×100

= (4/3 - 3/4) / 3/4 × 100

= (16-9)×4 / (3 × 4× 3) ×100

= 77.78%
