Question

There are 13 bicycles and 12 tricycles in the storage space of Vinay’s residential society. How many wheels are there in total?

• A. 56
• B. 42
• C. 62
• D. 72

Answer 1

The correct option is C

62

Number of wheels in a bicycle = $2$

Number of wheels in a tricycle = $3$

13 bicycles have $13\times 2.$

12 tricycles have $12\times 3.$

$\begin{array}{ccc}& 1& 3\\ & \times & 2\\ & 2& 6\end{array}$

and

$\begin{array}{ccc}& 1& 2\\ & \times & 3\\ & 3& 6\end{array}$

$\therefore$ Total number of wheels = $26+36=62wheels$
