Question

plz....solve the 5th problem the answer of this is 20%

Answer 1

Hey!!

CP of 12 bananas = ₹15
CP of 1 banana = ₹15/12 = ₹5/4

SP of 10 bananas = ₹15
SP of 1 banana = ₹15/10 = ₹3/2

SP > CP
$gain \: = \frac{3}{2} - \frac{5}{4} \\ = \frac{6 - 5}{4} \\ = \frac{1}{4}$
$gain\% = \frac{gain}{cp} \times 100 \\ = \frac{ \frac{1}{4} }{ \frac{5}{4} } \times 100 \\ = \frac{1}{4} \times \frac{4}{5} \times 100 \\ = 20\%$

Hope it helps!!
