Geeta can assemble a toy in 10 minutes. whereas Sudha can assemble the same Toy in 15 minutes. If they work together. How much time will they take to assemble 60 toys?

12 hours

Geeta = 10 min, Sudha = 15 min,

⇒ Time required by both of them to complete 60 toys together = \(\frac{60}{3+2}\) = \(\frac{60}{5}\) = 12 hours    ..(\(\frac{Work}{Efficiency}\) = Time)
