A man bought a horse for Rs.400 and cart for Rs.250. He sold cart at 20% profit and horse at 4% loss. Find gain or loss percent.

\par C.P. of horse = 400              \par loss = 4\%

\par S.P. = 400 \times \frac{100 - 4 }{100} = 400 \times \frac{96}{100} = 384

\par C.P. of cart = 250                \par gain = 20\%

\par S.P. = 250 \times \frac{100 + 20}{100} = 250 \times \frac{120}{100} = 300

\par C.P. of horse and cart = 400 + 250 = 650

\par S.P. of horse and cart = 384 + 300 = 684

\par Gain = 684 - 650 = 34as
a\par Gain\% = \frac{34}{650} \times 100 = \frac{340}{65} = 5.23
