three variables x,y,z have a sum of 30. all three of them are non-negative integers . if any two integers dont have same value and exactly one variable has a value equal or less than three .find number of possible solutiins
@scrabbler yes, the answer is 4. how did you go about this question? why is the angle on the base 90?
One of the sides is double the other and the included angle is 60...to 30-60-90 ban gaya na...:) I happily missed it and drew the figure and then realised ... regards scrabbler
zada has to distribute 15 choclates among her 5 kids(a,b,c,d,e) . such that "a" gets atleast 3 and at most 5 chocolates .in how many ways she can do this ?49577417435
C(15,3)+C(14,3)+C(13,3)????
but i am getting a very big answer from this...
i)let a gets 3 chocos
so b+c+d+e=12
combinations: C(15,3)
ii)when a gets 4 chocos
so b+c+d+e=11 combinations: C(14,3) iii)when a gets 5 chocos so b+c+d+e=10 combinations: C(13,3)
C(15,3)+C(14,3)+C(13,3)????but i am getting a very big answer from this...i)let a gets 3 chocosso b+c+d+e=12combinations: C(15,3)ii)when a gets 4 chocos so b+c+d+e=11combinations: C(14,3)iii)when a gets 5 chocos so b+c+d+e=10combinations: C(13,3)
bada aa rha hai...mere solution wo cases bhi include hai jab any kid can get 0 chocos also...is there any condition in question that each kid should get atleast 1 chocolate????
