(A) 49 years

(B) 53 years

(C) 51 years

(D) 47 years

1. If p is even and q is odd, then which of the following will necessarily be odd?

(A) p × q

(B) p + 2q

(C) p + q

(D) 2p + 2q

Explanation:

(a + 1/a)=√3

(a + 1/a)3 = a3 + 1/a3 + 3(a + 1/a)

=3√3-3√3=0

Explanation: Explanation:

40/100*3/4*4/5*x=48

X=200

1 % of x= 2

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

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

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

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.

Explanation: 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

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
