Answer 1

Answer:

• 1/10+1/12=6+5/60
• 60/11

Answer 2

Both Priya and Debu will complete the work "$\dfrac{60}{11}$ days".

Step-by-step explanation:

Priya's 1 hour's work = $\dfrac{1}{10}$ and

Debu's 1 hour's work = $\dfrac{1}{12}$

(Priya + Debu)'s 1 hour's work = $\dfrac{1}{10}$  + $\dfrac{1}{12}$

= $\dfrac{6 + 5}{60}$

= $\dfrac{11}{60}$

∴ Both Priya and Debu will complete the work = $\dfrac{60}{11}$ days.
