Question No 19

The sum of even numbers between 1 and 31 is:

Select the correct answer


Solution!
Let Sn = (2 + 4 + 6 + ... + 30). This is an A.P. in which a = 2, d = 2 and l = 30
Let the number of terms be n. Then,
a + (n - 1)d = 30
2 + (n - 1) x 2 = 30
n = 15.
Sn =n/2(a + l)=15/2x (2 + 30) = (15 x 16) = 240.

Question No 27

What is the unit digit in(795 - 358)?

Select the correct answer


Solution!
Unit digit in 795 = Unit digit in [(74)23 x 73] 
= Unit digit in [(Unit digit in(2401))23 x (343)] 
= Unit digit in (123 x 343) 
= Unit digit in (343) 
= 3
Unit digit in 358 = Unit digit in [(34)14 x 32] 
= Unit digit in [Unit digit in (81)14 x 32] 
= Unit digit in [(1)14 x 32] 
= Unit digit in (1 x 9) 
= Unit digit in (9) 
= 9
Unit digit in (795 - 358) = Unit digit in (343 - 9) = Unit digit in (334) = 4.
So, Option B is the answer.
