If the number is less than one, the zero on the right of decimal point but to the left of the first non-zero digit are not significant, i.e. in $\underline{\mathbf{0}} \underline{\underline{00} 764 \text {, }}$ the underlined zeroes are not significant. The number of significant digit is 3 . Both assertion (A) and reason ( $\mathrm{R}$ ) are correct and reason $(R)$ is the correct explanation of assertion (A).
