Hint: Sigma bonds are included in single bonds as well in the non-single bonds. Pi bonds are included in the double or triple bond.

We know that single bond $\left( {{\text{C}} - {\text{H}}} \right)$ includes one sigma bond and double$\left( {{\text{C}} = {\text{H}}} \right)$ and triple $\left( {{\text{C}} \equiv {\text{H}}} \right)$ bonds consists of one sigma bond and the remaining bonds are pi bonds. Let us number the sigma bonds and the pi bonds in the given compound.
Therefore, in the compound, $H - C \equiv C - C{H_2} - CH = C{H_2}$ there exist 10 sigma bonds and 3 pi bonds.
