Question

Kavita spent half the money she had on her dinner and half of that amount on movie tickets. She has now rupees 4 left. How much money did she have initially?

Answer 1

Answer:

Let total money = x

So, 1/2x is spent on dinner

1/2×1/2 i.e. 1/4x is spent on movie tickets

4 rs are remaining

So,

1/2x+1/4x+4=x

3/4x+4=x

4=4/4x-3/4x

4=1/4x

8=x

So,she had 8rs to begin with

Answer 2

Answer:

16 rs

Step-by-step explanation:

let her initial money be x

she used 1/2 of the money she had on dinner

and half of that on movie tickets (i.e., 1/2 x 1/2 = 1/4)

so,

1/2x + 1/4x + 4 = x

3/4x + 4 = x

x = 3/4x + 4

x - 3/4 x = 4

4/4x -3/4x = 4

1/4 x = 4

x = 4 x 4

x = 16

so, she had 16 rs (or whatever currency) to begin with.......
