↧↧↧ Detailed Video Solution to the Problem ↧↧↧


\((b\#a\#c)= ab-c\) and we need to find the value of \((4\#3\#5) + (6\#5\#7) =\)?

\((b\#a\#c)= ab-c\)
=> This is opened as a [\(2^{nd}\) term in \((b\#a\#c)\)] multiplied by b (\(1^{st}\) term) - c (\(3^{rd}\) term]

=> \((4\#3\#5) + (6\#5\#7)\) = (3*4 - 5) + (5*6 - 7) = 12 - 5 + 30 - 7 = 30

So, Answer will be D
Hope it helps!
