In a fort there is enough food sufficient for 1200 man 5 days how long the food would have last for if there would would have been thousand men.

Let food will last for X days.

As men and days are inversely proportional to each other so

X/5=1200/1000

X=1.2*5=5

X=6

Given that

1. A is the mother of B;

2. C is the son of A;

3. D is the brother of E;

4. E is the daughter of B.

The grandmother of D is

Hence, the answer is (a).

When a number is divided by 13, the remainder is 11. When the same number is divided by 17, then remainder is 9. What is the number ?

x = 13p + 11 and x = 17q + 9

13p + 11 = 17q + 9

17q - 13p = 2

q =(2 + 13p) /17

The least value of p for which q =(2 + 13p) /17is a whole number is p = 26

x = (13 x 26 + 11)

= (338 + 11)

= 349
