Given : y is directly proportion to x , and the value of y is 80 .

To Find : the value of x .

Answer : Take a constant K ,

then 60 = k = 6k (dividing both side by 6)

then we will get 10 = K

y = 10

y = 10\sqrt{x}

when y = 80 , then

80 = 10\sqrt{x} ( dividing both sides by 10 )

8 = \sqrt{x} ( squaring both sides )

64 = x

Hence , the value of x is 64 when y is 80
