∆ABC=∆DEF
AB=DE –>String
BC=EF–> Rib
m<C=m<F=90° –>List
AC=DF
So m<A=m<D=35 (It is not clear whether the number is 35 or 36, but the same number)

Answer:
Let us consider that ,
The worker can complete the work in x hours .
So, he can complete 1/x part of work in 1 hour.
Now, The workers does 2/3 of what he does. So they do 2/3(1/x) part of work in 1 hour . 2/3x work in 1 hour .
Consider them all working together,
So work done in one hour, = 1/x + 2/3x + 2/3x = 3 + 4 / 3x = 7/3x .
So, They taken 1 hour to complete 7/3th part of work. So, In 3x/7 hours , They all can complete the work.
Ratio of the time taken by all instead of only one = 3x/7 : x = 3/7 .
So ,The required option is 3/7
