@: krishnaprasad TATA: my friend,you haven't posted the right option the answer will be 2,because if 7 leg octopuses are 2,then total will be 14,and 5 will 8 leg octopuses
7x +8y =54
if we apply all above option,no one is matching the criteria,so right answers is 2.There are 2 seven leg octopuses does sangeetha calculate(ans)
