The squares of a 3 —3 grid of unit squares are coloured randomly and independently so that each square gets one of 5 colours. Three points are then chosen uniformly at random from inside the grid. The probability that these points all have the same colours can be expressed as a/b, where a and b are coprime positive integers. What is the value of a+b?

assuming this to be the right question
this will come as
ax^2+px^2+qx+c=0
product=-c/a
a=6
c=-6-24-60-120-210-336=-756
-c/a=126

@arunima88in Answer to q16 is wrong,in the first place.It should be c) if you want proof just do q18 or just see it, you will know.And about other questions, you can do all of them just by calculations.
@ankitkumaretn But how do solve it

My method of solving :

Revenue incurred in Apr 2020- (5* 600 * 50% + 10*350*45%)*30= Rs 92,250/-

Costs= Rs 1,00,000+ 10,000+(100*5+10*5)*30= Rs 1,40,000/-

Loss= Rs 47,750/- ????

LOD-III Q 19 Page 204 Q22


A restaurant has a pricing policy that allows for the following mark-ups :

Soups Markups 40%
Starters Markups 50%
Meals Markups 25%
Breads Markups 75%
Sweets Markups 75%

Q 22 Which of these are true :

(i) Profits increases if a part of the money spent on starters was spent on breads and another part of starters was spent on snacks.

(ii) Profits increases if a part of the money spent on meal items was spent on starters and another part on soups was spent on breads.

(iii) Profits decreases if a certain amount of the money (say x) spent on soups was spent on starters and the same amount (Rs x) of the spending on soups is spent on meal items.

a) ii) only b) iii) only c) ii) and iii) only d) All the three e) None of these


Ans c) ii) and iii) only

My doubt is : if we do not know the amount ( except iii) then how can we gauge the increase or decrease in price.

@Subhashdec2 I could nt follow 18) and 19) Why did you multiply 4/5 and why did you separately deducted the direct cost. i am confused that why direct costs are not included in the CP
@ScareCrow28 @shattereddream said:How many seven-digit numbers divisible by 11 have the sum of their digits equal to 59?1)40 2)55 3)34C3 Ä‚— 23C2 4)38C3 Ä‚— 26C2 5)None of these
Let the no be, (9-a)(9-b)(9-c)...(9-g)
Where the terms (9-a)...represent the digits
Now, 9-a + 9-b ....9-c = 59
=> a+b+c+d+e+f+g = 4
Also, 9-a+9-c+9-e+9-g-9+b-9+d-9+f = 11,22,33
=> (b+d+f) - (a+c+e+g) = 2, 13, ...
=> 2(b+d+f) = 6 OR (b+d+f) = 3
b+d+f = 3
Total = 5C2 = 10 ways
And, a+c+e+g = 1
Total = 4C3 = 4 ways
Total = 10*4 = 40 ways

can u plz explain why did u take no.s as (9-a)(9-b)(9-c)...(9-g)
and
"2(b+d+f) = 6 OR (b+d+f) = 3 "
and
" a+c+e+g = 1"
