Question

Arnold baked some buns. 3/4 of them were curry buns and the rest of them were tuna buns. he sold 5/6 of the curry buns and 63 of the tuna buns. In the end, only 1/5 of the buns were left.

How many buns did arnold makes?

Answer 1

too many!

Answer 2

x = no. curry buns

y = total no. buns

x =3y/4

y = 5x/6 + 63 + y/5

4y/5 = 5x/6 +63

24y = 25x  + 1890   (multiplying both sides by 30)

3y = 4x

32x = 25x + 1890

7x  =1890

x= 270

y= 360  which is the no. Arnold baked

Answer 3

I was going to solve,but the others on the top had already done.Its 360

Answer 4

Assume total buns he made=A

A-3/4*5/6*A-63=1/5*A

    A-15/24*A-63=1/5*A

(1-15/24-1/5)*A=63

                        A=360

He made total 360 buns.

Answer 5

Let total buns be B

Curry Buns - B*3/4

Tuna Buns - B*1/4

Buns Left - B*1/5

B - B*5/6*3/4 - 63 = B*1/5

B - B*5/8 -B*1/5 = 63

B*7/40 =63

B = 40*9 = 360

Answer 6

5/6 of the curry buns are 15/24 (or, by extension 225/360) of the total buns

Since 1/5 is 72/360, this means that the 63 tuna buns represent 63/360 of the total.  

So he made 360 buns

(EDIT: ouch, inched out by three seconds... that sucks.  Good job, mandeep)

Answer 7

c = 3t

c/6 + (t - 63) = (c + t)/5

5(3t/6 + (t - 63)) = (3t + t)

substituted 3t for c.  c is number of curry, t is number of tuna, and answer is c + t.  Solve for t and c.
