# For each pair of quantities given below, check whether the first is proportional to the second. For proportional quantities, calculate the constant of proportionality.

The interest got in any year and the amount deposited in a scheme in which interest in compounded annually.

Answer :

The interest got in any year and the amount deposited in a scheme in which interest in compounded annually.

Let the interest got in year be ‘i' and the amount deposited be p.

We know that,

i = p × r (where r is the rate of interest)

We can whatever value we like for p on right side of the above equation. So, p is a variable. But r is a constant for a scheme.

Whatever value we give for p, that the value will be multiplied by a constant r. So, i will always be proportional to p.
