Answer:
I have attached photo and explain
Step-by-step explanation:
Number of pages typed by Gorge in 1 hour
=508=254
Number of pages typed by Sonia in 1 hour
=506=253
Number of pages typed by Gorge and Sonia together in 1 hour
=(254+253)=(75+10012)=17512∴Required time=(100÷17512)hours=(100×12175) hours=487 hours=667 hours

Answer:
6 6/7 hrs
Step-by-step explanation:
we know,
work=men*hours*days
Given,
Harsh takes 8 hours to type a 50 page
50 pages=8 hrs
100 pages=16 hrs
while Prerna can type the same script in 6 hours.
50 pages=6 hrs
100 pages=12 hrs
together they can do,
1/16+1/12=7/48
48/7=6 6/7
