Question

Find the amount which when increased by 15% becomes 19320.
The cost price of 12 articles is equal to the selling price of 15 articles. Find the loss

​

Answer 1

Answer:

S.P. of 15 articles = C.P. of 12 articles

Let C.P. of 1 article = Re.1

C.P. of 12 article = Rs.12

and C.P. of 15 articles = Rs.15

S.P. of 15 articles = Rs.12

[S.P. of 15 articles = C.P. of 12 articles]

Loss = Rs.15 – Rs.12 = Rs.3

Loss% = \frac { 3 }{ 15 } x 100 = 20%
