Answer :23
Solution : books are between 15 and 30 if he gives to two of his friends then no. of books may be 17,19,21,23,25,27,29.again he give books to of his 3 friends then no. of books may be 17,23 and 29. Now he have to give books to of bhis 4 friends then no. of books will be 23.
Hence proved.

Answer:2
Explanation: 22^45 we will take base 2 here .so we will use cyclicity of 2 here. 45/4 gives remainder 1 so 2^1=2.
hence proved
Directions: Read the following information to answer the question.
(x – z) = odd – even = odd; y = odd. Odd × odd will always give odd, hence the first statement is wrong.
Directions: Refer the following data to answer the questions given below.
Since first and second varieties are mixed in equal proportions.
So, their average price = Rs.(126+135/2)=Rs.130.50
So, the mixture is formed by mixing two varieties, one at Rs. 130.50 per kg and the other at say, Rs. x per kg in the ratio 2 : 2, i.e., 1 : 1. We have to find x
By the rule of alligation, we have:
