Question

A woodcutter takes $12$ minutes in making over $3$ pieces of a block of wood. he will take $\underline{}$ minutes to makeover $5$ such pieces.

Answer 1

Given,

Time is taken to make $3$ pieces of block wood $=$$12minutes$

$3$ pieces$=$$12minutes$

Divide $3$ on both sides to get a piece of value.

$\frac{3}{3}$ piece $=$$\frac{12}{3}minutes$

$1$ piece $=$$4minutes$

Time is taken to make $1$ a piece of block wood$=$$4minutes$

Now multiply with $5$ on both the sides

$5\times 1$ pieces $=$$5\times 4minutes$

$5$ pieces $=$$20minutes$

Therefore, the time is taken to make $5$ pieces of block of wood $=$$20minutes$
