Question

Anushka can knit pair of socks in three days. Deepika can knit the same pair in nine days. If they knit together, in how many days can they knit two pairs of socks?

Answer 1

Answer:

Answer  = $4 \frac{1}{2}$ days

Step-by-step explanation:

Number of pairs knit by A and B together in 1 day

= $\frac{1}{3} + \frac{1}{9} = \frac{4}{9}$

∴ Required number of days,

= 2 / $\frac{4}{9}$

= 2 x $\frac{9}{4}$

= $\frac{9}{2}$

so they both can knit a pair of socks in $4 \frac{1}{2}$ days
