A) A grocer bought 20 kg of sugar at Rs 70 per kg. He sold 15 kg of sugar at Rs 75 per kg and the remaining quantity at Rs 69 per kg. Find his profit or loss percent

5%

Step-by-step explanation:

A grocer bought 20 kg of sugar at Rs 70 per kg. The total amount spent will be: = 20kg × Rs70 = Rs1400

He sold 15 kg of sugar at Rs 75

per kg and the remaining quantity at Rs 69 per kg. This will be:

= (15 × Rs75) + (5 × Rs69)

= Rs1125 + Rs345

= Rs1470

Gain = Rs1470 - Rs1400 = Rs70

Percent gain = Gain/cost price × 100

= 70/1400 × 100

= 1/20 × 100

= 5%

The profit percent is 5%

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
