Question

From a rope of length 40.50 m, some
$\text{pieces are cut each measuring}\frac{9}{4}m.$
Find the number of pieces cut.

• A. 15
• B. 18
• C. 22
• D. 9

Answer 1

The correct option is B

18

Converting all the lengths into centimetre.

Total length of the rope = 4050 cm,
Length of each piece
$=\frac{9}{4}\times 100=\frac{900}{4}$

Number of Pieces
$=\frac{Totallength}{Lengthofeachpiece}$

Number Of Pieces Cut
$=\frac{4050}{\frac{(9\times 100)}{4}}=18$

$=\frac{4050\times 4}{(9\times 100)}=18$

Number of pieces cut = 18.
