Answer is Rs. 144
Let us Consider Original i have amount of : X Rs
After Substraction (1/3) and (1/4) of Original Amount I Have Left With 60 Rs
So,
X - (\(X\over3\) + \(X\over4\)) = 60

X - (\(\frac{4X + 3X}{12}\)) = 60

X - (\(7X\over12\))=60

\(\frac{12X - 7X}{12}\) = 60

(12X - 7X) =60 * 12

5X = 720

X =144
