Prepare a grouped frequency distribution, taking class intervals as 10-14, 14-18 etc. From

the table find out the number of articles whose price is less than Rs 22.​

Answer 1

Answer:

cost/price of the article?

Let original cost price be _ RS 100.

Original selling price considering 20% profit _ RS 120

As per condition of the problem new selling price would be { 100–10}*130/100= RS 117

Therefore difference between two selling price will be 120–117 = Rs 3

Original cost price = 100/3 x 15

= RS 500 and new cost price would be 90/3x15= RS 450 ans
