Question

kanchan spends 1/2 of her money in one shop.she spends 1/3 of what was left with her on rickshaw fare. At the end ,she has rs20 with her. how much did she have in the beginning?

Answer 1

Let Kanchan have Rs X with her in the beginning.

     Then   Rs X/2 she is left with after shopping.
        Afterwards 1/3 of (X/2) is spent on rickshaw.
           So (1 - 1/3) rd of (X/2) is what she is left with.

     (2/3) * X/2 is left with her after rickshaw fare. 
            =>   X/3 = Rs 20
 
     So  she had  Rs 60. with her in the beginning.

Answer 2

Let Kanchan have ₹ X with her in the

beginning.

She spends ₹ X/2 in one shop.

Then, she spends 1/3 of (X/2) on rickshaw fare.

So, she is left with (1 - 1/3) of (X/2).

(2/3)* X/2 is left with her after rickshaw

fare.

=> X/3 = ₹ 20

So, she had ₹ 60 with her in the

beginning.
