A dealer bought a pendrive for rupees 500 he sold it at 10% loss if he wants to make a profit of 12.5 percent without increasing the selling price by how much should the cost price of the pendrive be reduced

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
