hugmon that a math made statement which is filled like this something in book i give the way the book says but i dont understand math english
here is a example
your friend has purchased 6 pencils of equal value for Rs(currency).you want to take two pencils from him what amount will you pay for that?to calculate the amount mentally you will first find the price of one pencil you can then calculate the price of the number of pencils that you want to have the price of one pencil is Rs 72 divided by 6.by multiplying the price of one pencil by 2 you then get the amount you are to pay the steps are:

Price of 6 pencils =Rs 72
1 pencil = Rs 72/6 = Rs 12
2 pencils=Rs 72/6*2=Rs 24
Rs 24 Ans
thats the way in book but these questions are last one the most tough

= 39 : 30
=1287 : x
x=(1287*30)/39
