Question : One man or two women or three boys can do a piece of work in 88 days. One man, one woman, and one boy will do it in:
Option 1: 44 days
Option 2: 24 days

Question : If $\theta$ is a positive acute angle and $4\sin^{2}\theta =3$, then the value of $\left (\tan\theta-\cot\frac{\theta}{2}\right)$ is:
Option 1: $1$
Option 2: $0$
Option 3: $\sqrt{3}$
Option 4: $\frac{1}{\sqrt{3}}$
Correct Answer: $0$
Solution : Given: $4\sin^{2}\theta =3$ $⇒\sin\theta = \pm\frac{\sqrt{3}}{2}=\sin 60°$ Since $\theta$ is acute, so, $\theta=60°$ So, $\tan\theta-\cot\frac{\theta}{2}=\tan60°-\cot30°=\sqrt3-\sqrt3=0$ Hence, the correct answer is 0.
Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Option 1: Only conclusion (II) follows
Option 2: Only conclusion (I) follows
Option 3: Both conclusions (I) and (II) follow
Option 4: Neither conclusion (I) nor (II) follows
Correct Answer: Neither conclusion (I) nor (II) follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some lilies are tulips – From the Venn diagram, it is evident that there is no direct relation between lilies

Option 1: solve the problem
Option 2: Let us think
Option 3: amiably
Option 4: how can we

Therefore, the correct
Question : The cost price of a cooler is Rs. 4800. If the profit percentage is 26%, what is the selling price of the cooler?
Option 1: Rs. 6248
Option 2: Rs. 6048
Option 3: Rs. 6640
Option 4: Rs. 5628
Correct Answer: Rs. 6048

Question : If $\frac{1}{x^{2}}+x^{2}$ represents the radius of circle $P$ and $\frac{1}{x}+x=17$, which of the following best approximates the circumference of circle $P$?
Option 1: $287\pi$
Option 2: $547\pi$
Option 3: $574\pi$
Option 4: $278\pi$
Correct Answer: $574\pi$
Solution : Given: $\frac{1}{x}+x=17$ Squaring both sides, we have, ⇒ $(\frac{1}{x}+x)^{2}=17^{2}$ ⇒ $\frac{1}{x^{2}}+x^{2}+2=289$ ⇒ $\frac{1}{x^{2}}+x^{2}=287$ Circumference of circle $P$ = $2\pi r$ = $2×\pi ×287$ = $574\pi $ Hence, the correct answer is $574\pi $.
