1.	A fruit _ seller bought banana at the rate of 3 for rs 8 and sold them 2 at the rate of 2 for rs.7 find his gain or loss percent!... don't spamexplain.please.
Answer» Answer: C.p of 3 BANANA = 8 s.p of 2 banana = 7 so, cp of 1 banana = 8/3 sp of 1 banana = 7/2 GAIN = s.p - c.p = $\frac{7}{2} - \frac{8}{3} \\ \\ \frac{21 - 16}{6} = \frac{5}{6} \\ \\$ gain% = $\frac{gain \times 100}{cp}$ $\frac{ \frac{5}{6} \times 100}{ { \frac{8}{3} } } \\ \\ = \frac{500 }{6 } \times \frac{3}{8} \\ \\ = \frac{500}{16} \\ = 31.25\%$

Answer:

C.p of 3 BANANA = 8

s.p of 2 banana = 7

so,

cp of 1 banana = 8/3

sp of 1 banana = 7/2

GAIN = s.p - c.p

$\frac{7}{2} - \frac{8}{3} \\ \\ \frac{21 - 16}{6} = \frac{5}{6} \\ \\$

gain% =

$\frac{gain \times 100}{cp}$

$\frac{ \frac{5}{6} \times 100}{ { \frac{8}{3} } } \\ \\ = \frac{500 }{6 } \times \frac{3}{8} \\ \\ = \frac{500}{16} \\ = 31.25\%$
