Sanjay buys packets of pens containing 12 pens in a packet he repacks from them into packets containing 10 pens in a packet he sold these packets of 10 at the same rate as he bought the pakets of 12did he make a profit what is the percentage of his profit

Yes, Sanjay made a 20% profit.

Step-by-step explanation:

Price of a pen bought by Sanjay = x

Price of packet of 12 pens bought by Sanjay = 12x

Price of packet of 10 pens sold by Sanjay = 12x

Price of pen sold by Sanjay = 12x/10 = 1.2x

Difference between price of pen sold and price of pen purchased = 1.2x - x = 0.2x

0.2 = 20%

Therefore, the profit per pen is 20%

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

3+x
