Answer: Rs 60
Step-by-step explanation:
Let Kanchan had x rupees in the begnning
x/2 of her money she spent in one shop then
she spent 1/3 of x/2
⇒ She spent 1/3 x x/2 = x/6 of her money.
According to the given condition
x/2 + x/6 + 20 = x
⇒ 3x + x - 6x = -20 / 6
⇒ -2x/6 = -20
⇒ x = 20x6/2 = Rs 60
Therefore Kanchan had Rs 60 in the beginning
