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;
[tex] x - 15 = \frac {3}{4} * x [/tex]
[tex] x - 15 = \frac {3x}{4} [/tex]
Cross-multiplying, we have;
[tex] 4(x - 15) = 3x [/tex]
[tex] 4x - 60 = 3x [/tex]
Rearranging the equation (collecting like terms), we have;
[tex] 4x - 3x = 60 [/tex]
x = Rs 60
Next, we find the amount left;
Amount left = 60 - 15
Amount left = Rs 45
