Condition should be.... Sum of two dice is divisible by 4 or 6.
Possible sums are 4,6,8,12.
Possible combinations to meet given conditions = 14
So probability =14/36= 7/18

Reply Like? Yes | No

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.

Devendra Marghade 5 years ago

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

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.

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

22 per kg so that there is a profit of 25% by selling the mixture @ Rs 23.90 per kg

Reply Like? Yes | No (1)

Devendra Marghade 5 years ago

Ans: 18 kg

Let x kg of wheat costing Rs. 14/kg is mixed, then (x*14 + 32*22)/(x+32) = 23.9*(100/125)
(14x + 704) / (x+32) = 19.12

Ans=5

Let the divisor be a, first no. be x and second no. be y, then in given 3 conditions
X = ak + 3 —(i)
y = al + 4 —(ii)
x+y = am + 2 —(iii)
Adding (i) & (iii), and Substituting x+y in (iii), we get (ak+3) + (al+4) = am+2
a(m-k-l) = 5
Prime factorization gives a=5 or 1
As divisor cannot be 1 in above given conditions, so divisor a=5.
