Given that p0 and p1 represent base and current prices of a commodity, q0 and q1 refer to the base and current quantities, then the formula used to calculate price relatives is :
1
\(\rm \frac{p_1}{p_0}\times 100\)
2
\(\rm \frac{p_1q_1}{p_0q_0}\times 100\)
3
\(\rm \frac{q_1}{q_0}\times 100\)
4
\(\rm\sqrt{p_{0} p_1}\)
