Question

if the price of a sweet is reduced by Rs 5, radha can buy 15 more sweets for Rs900. find the original price of sweet.

Answer 1

Price of 15 sweets= 900
01 sweet= 900/15= 60rs
the original price= given price + (the price. which is reduced=5)
=60+5
=65

Answer 2

Answer:

Rs.20

Step-by-step explanation:

Let the prize of one sweet be Rs. x

Let the no. of sweets be y  

So total amount spent = xy

Since we are given that the total cost is Rs.900

So,900 =xy   --1 (black line)

Now new price of 1 sweet = Rs. (x -5)

So,  no. of sweet  = y + 15  

So total amount spent =$(x - 5)(y + 15)$

Since we are given that the total amount remained same

$900 =(x - 5)(y + 15)$   --2 (Red Line)

Plotting these two equations we get the intersection point which is the solution of theses equations is (20,45)

So, x = 20

And x denotes cost of 1 sweet .

So, original price of a sweet is rs.20
