I=11−r21002

Answer 2

Step-by-step explanation:

Given:-

the original price of a toy was increased by 50% the price of one dozen toys was rupees 180.

To find :-

when the original price of a toy was increased by 50% the price of one dozen toys was rupees 180 what is the original price of one toy?

Solution:-

Let the original price of a toy = Rs. X

If it is increased by 50% then it becomes

=>X+50% of X

=>X+(50/100)X

=>X+X/2

=>(2X+X)/2

=>3X/2

Price of one dozen toys =180

According to the given problem

3X/2=180

=>3X=2×180

=>3X=360

=>X=360/3

=>X=120

Therefore,X=Rs. 120

Answer:-

The original price of the one toy =Rs. 120

Check:-

Original price =Rs. 120

If it is increased by 50% ,then it will be

=>120+50% ×120

=>120+60

=>180

and the price of a dozen toys =180
