Answer 1

I think answer 7 days...
p time taken days 6.9
and q is 30 per more than q so, he taken 2.07 days.. both can done work in 7 days..

Answer 2

Answer:

13 days

Step-by-step explanation:

Work done by P in 1 day = 1/23

Let work done by Q in 1 day = q

q × (130/100) = 1/23

=> q = 100/(23×130) = 10/(23×13)

Work done by P and Q in 1 day = 1/23 + 10/(23×13) = 23/(23×13)= 1/13

=> P and Q together can do the work in 13 days
