Question

The length of a rope is decreased by 5 percent .what is its new length , if it was 200m long​

Answer 1

Answer:

190 m

Step-by-step explanation:

5% of 200 m = 5/100 x 200

                      = 10 m

So,

New length = Old length - Decreased length

                    = 200 - 10 m

                    = 190 m

Answer 2

Answer:

190 m

Step-by-step explanation:

Length of rope decrease = 5%

Length of rope before decreasing = 200m

Length decrease of rope =

5/100 × 200

1/20 × 200

10m (size decreased)

New length of rope = 200m - 10m

= 190m
