Question

Roby buys 3 ropes. Each rope is 2 yards long. If 10 inches are lost in tying knots. What is the length of rope left in inches?
[ Hint:1 yard = 36 inches ]

• A. 206 inches
• B. 216 inches
• C. 200 inches
• D. 272 inches

Answer 1

The correct option is A 206 inches

$\text{2 yards =}2\times 36=72inches$
$\text{Length of 3 ropes =}3\times 72=216inches$

Remaining rope = Total length of 3 ropes - Rope lost in tying knots
i.e.

206 inches of rope were left.
