Question : The total number of prime factors in $4^{10}\times 7^{3}\times 16^{2}\times11\times 10^{2}$ is:
Option 1: 34
Option 2: 35
Option 3: 36
Option 4: 37
Correct Answer: 36
Solution : Given: $4^{10}\times7^{3}\times16^{2}\times11\times10^{2}$ Rewrite this equation with the prime factors. $(2^{2})^{10}\times7^{3}\times(2^{4})^{2}\times11\times2^{2}\times5^{2}$ = $2^{20+8+2}\times7^{3}\times11^{1}\times5^{2}$ = $2^{30}\times7^{3}\times11^{1}\times5^{2}$ Total number of prime factors = 30 + 3 + 1 + 2 = 36 Hence, the correct answer is 36.
Question : If three angles of a triangle are (2y + 40°), (5y – 60°), and (3y – 80°). Then what is the value of y?
Option 1: 30°
Option 2: 24°
Option 3: 28°
Option 4: 26°
Correct Answer: 28°
Solution : Given: Three angles of a triangle are (2y + 40°), (5y – 60°), and (3y – 80°). We know that the sum of all three angles of a triangle is 180°. Then, (2y + 40°) + (5y – 60°) + (3y – 80°) = 180°

Option 1: 15 years
Option 2: 18 years
Option 3: 20 years
Option 4: 30 years
Correct Answer: 20 years
Solution : Let the sum be P. Total amount after 10 years = 2P Simple Interest in 10 years = 2P – P = P If total amount = 3P, Simple Interest = 2P Using the unitary method, Since, in 10 years interest is P Therefore,

Question : The average of 10 consecutive integers is $\frac{11}{2}$. What is the average of the "smallest four" of these integers?
Option 1: 2.5
Option 2: 3.5
Option 3: 3
Option 4: 2
Correct Answer: 2.5
Solution : Let the 10 consecutive integers be $x, (x + 1), (x+2), (x+3), (x+4), (x+5), (x+6), (x+7), (x+8),(x+9)$ Average $=\frac{x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)+(x+7)(x+8)(x+9)}{10} = \frac{11}{2}$ ⇒ $10x + 45 = \frac{11}{2} × 10$ ⇒ $10x = 55 - 45$ ⇒ $x = \frac{10}{10} = 1$ The Smallest four integers

Question : If $p^{3}+3p^{2}+3p=7$, then the value of $p^2+2p$ is:
Option 1: 4
Option 2: 3
Option 3: 5
Option 4: 6
Correct Answer: 3
Solution : Given that: $p^3 + 3p^2 + 3p = 7$ Adding unity to both sides, $p^3 + 3p^2 + 3p + 1 = 7 + 1$ ⇒ $(p+1)^3 = (2)^3$ ⇒ $p+1=2$ ⇒ $p = 1$ $\therefore p^2 + 2p = 1 + 2 \times 1
