B7 days

C9 days

and

B 1 day's work = 1/15

So (A + B) 1 day's work = (1/10+1/15)

= (3/30+2/30) = 5/30 = 1/6

So Both (A & B) together can finish work in 6 days

A1/7

B1/6

A's 1 day's work = 1/18

and

B's 1 day's work = 1/9 (B can do work in half time)

(A + B)'s 1 day's work = (1/18+1/9)

= (1+2)/18 = 3/18 = 1/6

so A & B together can do 1/6 of work in 1 day.

**In C programming language, *p represents the value stored in a pointer and p represents the address of the value, is referred as a pointer. const char* and char const* says that the pointer can point to a constant char and value of char pointed by this pointer cannot be changed.**

** const char *ptr : This is a pointer to a constant character. You cannot change the value pointed by ptr, but you can change the pointer itself. “const char *” is a (non-const) pointer to a const char.**

**char *const ptr : This is a constant pointer to non-constant character. You cannot change the pointer p, but can change the value pointed by ptr. **
