Choose the correct option.

A can do a work in 10 days and B can do the same work in 15 days. So how many days they will take to finish the same work ?


A5 days

B7 days

D6 days

Answer: Option D

Explanation:

First find the 1 day work of both (A & B)
A 1 day's work = 1/10
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.

ShortCut By :: sudhan

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.
