FOR MAKING 20 LARGE CAKES WE NEED 10 HELPERS,WHILE TO MAKE 700 SMALL CAKES WE NEED 20 HELPER, TOTAL 30 HELPER NEEDED BUT IN 1 HR THEY MADE AS REQUIRED....
THE KITCHEN IS AVAILABLE FOR 3 HR SO WE NEED 30/3=10 HELPER....

In 1 hour 2 large cakes by 1 helper
therefore, 20 latge cakes are made bye 20/2= 10 people in 1 hour.
Remaining is 2 hours in which 700 small cakes r to be made.

If in 1 hour 35 small cakes can be made, then in 2 hours 70 cakes can be made by 1 helper.
therefore to make 700 small cake in 2 hour, we need 10 helpers. in 1st 1 hour ten helper hv cmpleted dere work..so they are free to complete rest f work in 2 hour.
Thus, the answer is a.10 :)
