Question

Ali has two pieces of ropes, A and B. Their lengths are in the ratio of 3:5. Rope A is 90m long. If Ali cuts 20m from Rope B,what is the ratio of length of Rope A to that of Rope B which is remaining?​

Answer 1

Answer:

9:13

Step-by-step explanation:

Let the length of Rope B be x cm

3/5 = 90/x

x = 90 * 5 / 3

  = 150

Now 20m is cut from rope B.

150 - 20 =130

Ratio = 90/130

         = 9/13
