Question

factorise 3xy-62y-3x+6z​

Answer 1

Sorry but i think the question was "3xy-6zy-3xt+6zt" otherwise the question you have stated is impossible to factorize.

"3xy-6zy-3xt+6zt

factorization consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.

Solution for the above factorization problem is:

Group in order to get common factor in each group

3xy - 6zy - 3xt + 6zt = (3xy - 3xt) + (6zt - 6zy)

Take common factor outside

= 3x (y-t) + 6z (t-y)

Simplify

= (3x + 6z) (y - t)

hope, it may help you!!

Answer 2

Answer:

Let us suppose,

C.P of an article is RS.100

And Profit%=35%

Then,S.P of the article=Rs.135

Now,M.P of an article be Rs x

Here, Discount%=5%

Therefore, S.P=MP-D%of M.P

        or,Rs 135=Rs x-10/100*Rs x

        or,Rs 135=Rs 9x/10

        or,9x=1350

        or,x=1350/9=150

Therefore,x=Rs 150

(NOTE) If an article isnt sold at by giving any discount.Then,

            at that condition Seller used to sold it on M.P

So, S.P=Rs 150

      C.P=Rs 100

Then, profit%=(SP-C.P)/C>P*100%

                     =50/100*100%

                     =50%
