Correct Answer: Rs. 750

Solution : Given: A certain sum becomes Rs. 1,050 in 5 years and Rs. 1,230 in 8 years at simple interest.
So, simple interest for 3 years = 1230 – 1050 = 180
$\therefore$ simple interest for 5 years = $\frac{180}{3}$ × 5 = 300
So,

Correct Answer: 2

Solution : In the original sentence, the verb "make" is used, meaning to create or produce jokes. However, a more suitable verb is "crack," which means to tell or share jokes.

Correct Answer: $a^2+b^2$

Solution : Given: $x=a\cos\theta + b\sin\theta$ and $y=b\cos\theta-a\sin\theta$
To find: $x^{2}+y^{2}$
Putting the value of $x$ and $y$, we get
$(a\cos\theta+b\sin\theta)^{2}+(b\cos\theta-a\sin\theta)^{2}$
 $(a^2\cos^2\theta+b^2\sin^2\theta+2×a\cos\theta×b\sin\theta)+(b^2\cos^2\theta+a^2\sin^2\theta-2×b\cos\theta×a\sin\theta)$
$=a^2\cos^2\theta + b^2\sin^2\theta+b^2\cos^2\theta+a^2\sin^2\theta$
$=a^2(\cos^2\theta+sin^2\theta)+b^2(sin^2\theta+\cos^2\theta)$
We know that, $(sin^2\theta+\cos^2\theta)=1$
Thus, $a^2(1)+b^2(1)$= $a^2+b^2$
Hence, the correct answer is $a^2+b^2$.

Correct Answer: 700

Solution : The average production of rice per year from 2009 to 2011
= $\frac{540+720+840}{3}$
= $\frac{2100}{3}$
= 700 tonnes
Hence, the correct answer is 700.

61, 73, 99, 141, 201, (?)

The pattern is as follows –

So, the required number in the series is 281. Hence, the first option is correct.

Correct Answer: E

Solution : Given:
Q, O, M, K, I, G, ?

Subtract 2 to the place value of each letter to get the next letter of the series.
Q – 2 = O; O – 2 = M; M – 2 = K; K – 2 = I;
