Answer»

Answer:

(a) 900

(b)1200

let no. of row =x

no. of seats in one row=y

total seats hence =xy

A.T.Q

x=y

also 2x .(y-10) =xy+300 •••••••1

put x=y in EQ 1

substitution method

2x.(x-10)=x.x+300

2x^-20x=x^+300

x^-20x-300=0

(x-30)(x+10)=0

x=30. (10 is neglected as no. of rows CANT be negative)

hence initial seats =xy

=x^

=30.30

=900

seats after NEW arrangement = xy+300

43.

If a+b+c=0 then find the value of a^2+b^2+c^2/a^2-bc

Answer»

ANSWER:

a+b+c=0

a=−b−c ..........(1)

(a+b+c) 2=0

a+2+b+2+c

2+2(ab+bc+ca)=0

K(a 2−bc)+2(ab+bc+ca)=0

2(ab+bc+ca)=−K(a(−b−c)−bc)

⟹2(ab+bc+ca)=K(ab+bc+ca)

⟹K=2

44.	Manufacturer has 600 litres of a 12% solution of acid. How many litres of a 30% acidsolution must be added to it so that the acid content in the resulting mixture will be more than 15% but less than 18%?
Answer» Answer: PLEASE MARK MY ANSWER AS BRAINLESIT let's "X" liters of 35% acid solution is required to be added Then Total mixture = (x + 600) liters. Therefore, 30% x + 12% of 600 > 15% of (x+600) 30x/100 + 12/100 (600)> 15/100 (x+600) and 30x/100 + 12/100(600) < 18/100 (x+600) 30x + 7200 > 15x + 9000 and 30x + 7200 < 18x + 10800 15x > 1800 & 12x <3600 x > 120 & x < 300 Thus the no of 30% solution acid should be more than 120 liters but less than 300 liters

Manufacturer has 600 litres of a 12% solution of acid. How many litres of a 30% acidsolution must be added to it so that the acid content in the resulting mixture will be more than 15% but less than 18%?

Answer»

Answer:

PLEASE MARK MY ANSWER AS BRAINLESIT

let's "X" liters of 35% acid solution is required to be added

Then

Total mixture = (x + 600) liters.

Therefore,

30% x + 12% of 600 > 15% of (x+600)

30x/100 + 12/100 (600)> 15/100 (x+600)

and 30x/100 + 12/100(600) < 18/100 (x+600)

30x + 7200 > 15x + 9000

and

30x + 7200 < 18x + 10800

15x > 1800 & 12x <3600

x > 120 & x < 300

Thus the no of 30% solution acid should be more than 120 liters but less than 300 liters
