Varun 5 years ago

(1) Lets just first select from 1 variety,
In 5 ways one or more of same variety can be picked {1,2,3,4,5}
We have 6 such varieties

(2) Now lets go to second variety,
Additionally,
Picking from second variety can be done in 6 ways including picking zero {0,1,2,3,4,5,6}
And we have 5 such extra varieties
= 5*6*6*5 = 900

Two articles A and B, with the same marked price were sold at 15% and 12% discounts respectively. Percentage of the profit earned on articles A and B was 6.25% and 20% respectively. The cost price of article B was Rs.160 less than the cost price of article A. Find the marked price of the each article.

Let the CP of A=x+160 and B=x. Marked Price of A and B=P.
Then, SP of A = P*85/100 = (106.25/100)* (x+160) ---> 17P = (x+160)*21.25 ---(i)
SP of B = P*88/100 = (120/100)*x ---> 11P = 15x ---(ii)
Solving (i) & (ii), we get Marked Price = P=2400 and CP of B=x=1760, CP of A=(x+160)=1920

Hi, looking for feedback regarding the following question:
There are 500 candies. If 350 have sprinkles and 300 have chocolate chips, and at least 60 have neither sprinkles nor chocolate chips, the number of candies that have both is in this range:
a)40 and 120
b)80 and 180
c)180 and 320
d)210 and 300
e)300 and 350
This question is from this site and I've also placed my reasoning/solution for it.
Any help will be most appreciated.
Joy

It is 210 and 300
Total candies 500
Out of these candies with both maximum is 300. Since chocklet chips is subset to sprinkles.
60 is neither of them. So either of them are 500-60=440
Now minimum =350+300-440=210
So it will be 210 and 300

Let the ratio is x:y

2x+4y=3x+3y=>x=y
Now x:y=1:1
