A
sells an article to B at a profit of 20% and B sell it to C at a profit of 25%.
If C pays rs. 1200, then the cost price of the article originally is?

Two numbers are in the ratio of 3:5. If 9 be subtracted from each, then they are in the ratio of 12:23. Find the number? a. 15:28 b. 36:115 c. 33:55 d. 60:69

Also can solve as> a+b+ab/100

ReplyDeleteSo. > 20+25+ 20*25/100

= 45+ 500/100

=50

Over all 50% profit.. so 150 units =1200

Soo 100 units =800..
