during sher a showroom offers a discount of 25% on each item what would a customer have to pay for a pair of jeans marked at Rs 1990 and 2 shirts at Rupees 1500 each

Answer»

Discount=25 PERCENT

SELLING price =100-25

=75 percent

Jeans=1990

100 percent=1990

1 percent =1990/100

= 19.9

75 percent =19.9*75

1492.5

Therefor price of jeans=1492.5

SHIRT=1500

100 percent=1500

1 percent =15

75 percent = 15*75

=1125

Therefor 1 shirt =1125

24.	If the equation 5x + ky =3 and kx + 5y = 3 represent the same line then k=?
Answer» Answer: k = 5 Step-by-step EXPLANATION: we have a1x + b1y + C1 = 0 and a2x + b2y + C2 = 0 so a1 = 5, B1 = k , c1 = -3 a2 = k, b2 = 5, c2 = -3 a1/a2 = b1/b2 or 5/k = k/5 k^2 = 25 or k = 5 b1/b2 = k/5 = 5/5 = 1 c1/c2 = -3/-3 = 1 Now a1/a2 = b1/b2 = c1/c2 = 1 hence k =5

24.

If the equation 5x + ky =3 and kx + 5y = 3 represent the same line then k=?

Answer»

Answer:

k = 5

Step-by-step EXPLANATION:

we have a1x + b1y + C1 = 0 and a2x + b2y + C2 = 0

so a1 = 5, B1 = k , c1 = -3

a2 = k, b2 = 5, c2 = -3

a1/a2 = b1/b2 or 5/k = k/5

k^2 = 25 or k = 5

b1/b2 = k/5 = 5/5 = 1

c1/c2 = -3/-3 = 1

Now a1/a2 = b1/b2 = c1/c2 = 1

hence k =5
