Following questions are completely based upon numbers. In the test, every question consists of four numbers labeled as option A, B, C and D. Your task is to find out the group of digits which contains a “9”. If digit “9” exists in any number (option) then your answer is that option. If more than one number (option) has digit 9, the answer will be E.
A.2822032 B.1475015 C.2578081 D.3933061
1). A
2). B
3). C
4). D

1). 25
2). 10
3). 12
4). 20
In the following questions, some numbers are given at the left side and some are at the right side too. If numbers of both sides are same, then answer would be ‘Y’ (Yes) and if numbers are different the answer will be ‘N’ (No).
A. 190528 B. 190628
1). Y
2). N
3).
4).
If tan A = 1 and tan \(B = \sqrt 3 \) then value of cos (A + B) is
1). \(\frac{{1 + \sqrt 3 }}{{2\sqrt 2 }}\)
2). \(\frac{{1 - \sqrt 3 }}{{\sqrt 2 }}\)
3). \(\frac{{1 - \sqrt 3 }}{{2\sqrt 2 }}\)
4). \(\frac{{1 + \sqrt 3 }}{4}\)
Find the sum of the given terms.
\(\frac{1}{{\left( {{2^2} - 1} \right)}} + \frac{1}{{\left( {{4^2} - 1} \right)}} + \frac{1}{{({6^2} - 1)}} + ... + \frac{1}{{({{20}^2} - 1)}}\)
