Hey dear here is your answer.....
This answer is verified ✅✅
A can do 1/3 of work in 5 days
A can do full work in = 5×3= 15 days
so in one day A can complete 1/15 of work.
B can do 2/5 of work in 10 days
B can do full work in 5×10 = 50 days
so in one day B can complete 2/50 of work
If A and B together for one day, part of work can be complete as
= 1/A + 1/B
= 1/15+2/50
= (10+6)/150
= 16 /150
= 8/75
so in one day, A and B together can complete 8/75 of work
Hope it will help you......

Answer:
9 3/8
Step-by-step explanation:
a can do 1/3 of work in 5 days
i.e,1/3 *1/5=1/15
b can do 2/5 of work in 10 days
i.e,2/5 * 1/10 =2/50 =1/25
a+b=1/15 + 1/25
=>(5+3)/75
=>8/75
can be written as 75/8
=>9 3/8
