(b) How much the selling price should be fixed for pulse bought for Rs.70 per kg. to earn a profit of Rs.6 after allowing a 5 %
Mama L [17]

Answer:

Rs. 80

Step-by-step explanation:

Given that :

Purchase price = 70

Profit = 6

Discount = 5%

Let selling price = x

Selling price * (1 - discount) = (purchase price + profit)

x * (1 - 5%) = (70 + 6)

x * (1 - 0.05) = 76

x * 0.95 = 76

0.95x = 76

x = 76 / 0.95

x = 80

Hence, selling price = Rs. 80

Find the length of CD A. 6 meters B. 7 meters C. 8 meters D. 9 meters
shutvik [7]

Answer:

D. 9 meters

Step-by-step explanation:

AB = CD, so 9x-27=2x+1.

If you get like terms on the same side you get 7x=28

If you simplify by dividing everything by 7, you get x=4

If you plug 4 in as x into the expression 2x+1, you get 9.
