Question

Rehana has some money after she spend Rs15 she has Three quarter of the initial amount left the amount left is

Answer 1

Amount left = Rs 45

Explanation:

Let the initial amount be x.

Translating the word problem into an algebraic expression, we have;

`x - 15 = \frac {3}{4} * x`

`x - 15 = \frac {3x}{4}`

Cross-multiplying, we have;

`4(x - 15) = 3x`

`4x - 60 = 3x`

Rearranging the equation (collecting like terms), we have;

`4x - 3x = 60`

x = Rs 60

Next, we find the amount left;

Amount left = 60 - 15

Amount left = Rs 45
