Answers:
- Answer: A
Explanation:
(a + 1/a)=√3
(a + 1/a)3 = a3 + 1/a3 + 3(a + 1/a)
=3√3-3√3=0
- Answer: C
Explanation:
- Answer: B
Explanation:
40/100*3/4*4/5*x=48
X=200
1 % of x= 2
- Answer: C
Explanation:
log 27 = 1og 33
3·log 3 = 1·431
⇒ log 3 = 1·431/3
∴ log 9 = log 32 = 2 log 3 = 2 × 1·431/3 = 2·862/3 = 0·954
- Answer: B
Explanation:
First term of geometric progression = a
Sum of eight terms G. P. = a (38 – 1) / (3 – 1) = 6560
∴ a = 2 × 6560/ (38 – 1) = 2 × 6560 / (6561 – 1) = 2
- Answer: D
Explanation:
Rise in average after 17th innings = 3 × Total increase in runs after 17th innings = 3 × 17 = 51
The player scored 85 runs in 17th innings.
∴ His average of runs till 16th innings = 85 – 51 = 34
∴ Average of all 17 innings = 34 + 3 = 37
- Answer: D
Explanation:
Sum of all interior angles of a polygon of ‘n’ sides is (n–2) × 180o.
So, for ‘8’ sides, it is 6 × 180o = 1080o.
- Answer: D
Explanation:
- Answer: D
Explanation:
Sum of ages of P and Q = 42 × 2 = 84 years.
Sum of ages of R and S = 52 × 2 = 104 years.
So, average of ages of P, Q, R and S = (84+104)/4=47
- Answer: C
Explanation:
p × q = even × odd = even
p + 2q = even + 2 × odd (even) = even
p + q = even + odd = odd
2p + 2q = 2 × even (even) + 2 × odd (even) = even
