Question

S varies inversely as the cube root of t. When t=8, s=2. Find s when t=64. b) The cost of soyabean is directly proportional to its weight. If cost of 9kg of soyabean is Rs540 then find the cost of 1 quintal soyabean. (1 quintal= 100 kg)​

Answer 1

Given that, the cube root of x varies inversely as square of y

⟹3x∝y21 or

3x=k.y21       …(1), where k is a constant.

Given that, x=8 and y=3

    ∴38=k×(3)21

           2=k×91

⟹k=18        …(2)

Now, if y=121=23

From (1) and (2):

3x=18.y21

3x=18×(23)
