Question

if rajiv type 480 letters in 6 minutes and shivani can type 324 letters in 270 seconds,then both can type how many letters in 12 minutes
please answer me as fast as you can

Answer 1

Answer:

Rajiv can type 480 letters in six minutes

Per minute letters of Rajiv = 480/6 = 80

Shivani can type 324 letters in 270 seconds (i.e 270/60 min)

Per minute letters of Shivani= 324/(270/60) = 72

Therefore,

Per minute letters typed by them together = 80+72= 152

Letters types by them together in 12 min = 12 x 152 = 1824

Ans: Rajiv and Shivani type together 1824 letters in 12 minutes.

Hope it helps!!
