Answer 2

Here's ur answer :

value of x = 6

it is given that, x varies directly as y.

i.e., x ∝ y ⇒x = ky , where k is proportionality constant.

given, x = 7 and y = 14/5

so, 7 = k (14/5) ⇒k = 5/2

hence, x = (5/2)y

now we have to find x when y = 12/5

i.e., x = (5/2) × 12/5 = 6

hence, value of x = 6.
