Question : Directions: In this question, three statements are given, followed by two conclusions. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follows/follow from the statements. Statements: I. No streak is a line. II. Some lines are bonds. III. All bonds are flashes. Conclusions: I. Some flashes are streaks. II. No flash is a line.
Option 1: Only conclusion I follows
Option 2: Both conclusions I and II follow
Option 3: Only conclusion II follows
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 flashes are streaks – From the above diagram, it can be seen that there is no direct relation between
Question : In a bucket, there are 40 red balls and 120 blue balls. The ratio of red to blue is:

Question : The difference between compound interest and simple interest on a sum of Rs. 16,000 for two years is Rs. 160. Find the per annum rate of interest.
Option 1: 12%
Option 2: 10%
Option 3: 11%
Option 4: 15%
Correct Answer: 10%
Solution : Given: Principal = Rs. 16,000 Time = 2 years We know, Difference between compound interest and simple interest = $P(\frac{r}{100})^2$, where $P$ = Principal, $r$ = Rate of interest ⇒ $160=16000(\frac{r}{100})^2$ ⇒ $\frac{r^2}{10000}×100=1$ ⇒ $r^2=100$ $\therefore r =10$% Hence, the correct answer is 10%.
Question : Directions: In this question, some equations are solved on the same basis as a certain system. On the same basis, find out the correct answer out of the four alternatives for the unsolved equation. If, 64 + 7 = 460 and 25 + 8 = 212, then 43 + 8 = ?
Option 1: 360
Option 2: 376
Option 3: 332
Option 4: 356
Correct Answer: 356
Solution : Given: 64 + 7 = 460 and 25 + 8 = 212
Like, 64 + 7 = 460→(64 × 7) + 12 = 448 + 12 = 460 And, 25 + 8 = 212→(25 × 8) + 12 = 200 + 12 = 212 Similarly,
Question : Three years ago, Raman’s salary was INR 45,000. His salary is increased by 10 percent, A percent and 20 percent in the first, second and third year respectively. Raman's present salary is INR 83,160. What is the value of A?
Option 1: 50
Option 2: 30
Option 3: 54
Option 4: 40
Correct Answer: 40
Solution : Given: Three years ago, Raman’s salary was INR 45,000. According to the question, 45000 × (100 + 10)% × (100 + A)% × (100 + 20)% = 83160 ⇒ 45000 × $\frac{11}{10}$ × (100 + A)% × $\frac{6}{5}$ = 83160 ⇒ (100 + A)% =
Question : If $\sec \theta+\tan \theta=3$, then the value of $\sec \theta$ is:
Option 1: $\frac{4}{3}$
Option 2: $\frac{3}{4}$
Option 3: $\frac{3}{5}$
Option 4: $\frac{5}{3}$
Correct Answer: $\frac{5}{3}$
Solution : Given: The value of the trigonometric equation is $\sec \theta+\tan \theta=3$. We know that if $\sec \theta+\tan \theta=x$. Then, $\sec \theta–\tan \theta=\frac{1}{x}$. $\sec \theta+\tan \theta=3$ (equation 1) ⇒ $\sec \theta–\tan \theta=\frac{1}{3}$ (equation 2) Adding equation 1 and equation 2, $\sec \theta+\tan \theta+\sec \theta–\tan \theta=3+\frac{1}{3}$ ⇒
