Question

total of aniket marks in maths and science together are 100 more than his marks in english.his average markes in tha three subjects are 60.what are his marks in english

Answer 1

what kind of name is aniket? ok back to the question, i'm not sure how to explain to you how i solved this one but i did find the answer. I just made one of his subjects marks 60 then i subtracted 20 from 60 and added 20 from 60 so the three mark amounts are 40,60,80. So his marks for english are 40 because 60+80=140-100=40

Answer 2

40

Answer 3

first we consider the mark of english be ' x ' .
Now the average of three subject is (100+x+x)/3

Now by the gien condition we get ,


(100+2x)/3 =60
100+2x =180

2x = 180-100
x = 80/2
x = 40
