Suppose , the number of bananas he bought be 60 (L.C.M. of 12 and 20)
So he bought the bananas for
$56 \times \frac{60}{20} = 168$
And sold it for
$35 \times \frac{60}{12} = 175$
Gain = SP - CP
= 175 - 168
= 7

$gain\% = \frac{gain}{cp} \times 100 \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{7}{165} \times 100 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 24\%$
