Let the amount available with lady is Rs x
Amount spend for hankies and given to bagger = \(\frac{x}2\)+1
Remaining amount = x - \((\frac{x}2+1)=\frac x2-1=\frac{x-2}2\)
Expences for lunch \((\frac{x-2}2)\times \frac 12\) = \(\frac{x-2}4\)
Amount of tip = Rs 2
Amount remained after lunch = \((\frac{x-2}2)-\frac{x-2}4-2\)
= \(\frac{2x-4-x+2-8}4\) = \(\frac{x-10}4\)
Amounts spend for books = \(\frac 12\times\frac{x-10}4=\frac{x-10}8\)
Bus fare = Rs 3
Amount left = \(\frac{x-10}4-\frac{x-10}8-3\)
= \(\frac{2x-20-x+10-24}8=\frac{x-34}8\)
According to the question amount left = Re 1
\(\frac{x-34}8=1\)
On cross multiplication, we get
x - 34 = 8
x = 42
Therefore original amount with lady was Rs. 42
