Question

3. Rama alone can knit a pair of socks in 6 hours and Anjali can knit a pair of socks in 8 hours. How
much time would they take working together to knit a pair?​

Answer 1

Answer:

I guess 7 hours

Step-by-step explanation:

Because

Rama time: 6 hours for two pair of socks

Rama time for 1 single sock: 6/2=3

Anjali time: 8 hours for two pair

Anjali time for 1 single sock: 8/2=4

So, together time to knit a pair = 4+3

                                                   =7 hours

Answer 2

Answer:

Rama and Anjali can complete the work in 3 3/7 hours

Step-by-step explanation:

Rama's work in 1 hour = 1/6 hour

Anjali's work in 1 hour = 1/8 hour

Rama + Anjali's work in 1 hour = 1/8 + 1/6 = 7/24

      = 7/24 = 24/7                (Reciprocating the values)

⇒ Rama and Anjali take 24/7 hours which is 3 3/7 hours.
