Question

If rajiv can 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 ?

Answer 1

Answer:

1824 letters

Step-by-step explanation:

Rajiv can type 480 letters in 6 mins

in 1 minute he can type = 480/6 = 80 letters

in 12 mins Rajiv can type = 80 × 12 = 960 letters

Shivani can type 324 letters in 270 secs

270/60 = 4.5 mins

324 letters in 4.5 mins

in 1 minute Shivani can type = 324/4.5 = 72 letters

in 1 minute Shivani can type = 72 × 12 = 864 letters

together they can type in 12 mins

960 + 864 = 1824 letters
