I<br> f the cost of 10 pens is rs 300,how much more is the cost of 2 dozens.
geniusboy [140]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Find the cost per pen by dividing:

300/10 = 30

It costs rs 30 for one pen

1 dozen = 12

2 dozens = 24

Multiply the values:

24 x 30 = 720

The cost of 2 dozen pens is rs 720

However, as it is asking for 'how much more' you have to subtract:

720 - 300 = 420

The cost is rs 420 more

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
