Question

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

Answer 1

Answer:

Amount left = Rs 45

Step-by-step 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
