Ram sold tp shyam an article with 20 percent profit .Shyam sold same article for rs.504 with 5percent profit to ghanshyam. How did it cost for eam?

25%

Step-by-step explanation:

Let the original cost price (CP) be x.

Selling price (SP) for Shyam (Shyam buying) =x(p100+1) where p is the profit percentage.

Selling price for Mohan =x(p100+1)(p100+1)

Selling price for Rakesh =x=(1−0.36)×x(p100+1)(p100+1)

⟹(p+100)2=100000.64

⟹p+100=1000.8=125

⟹p=25%

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
