Question : The smallest among the numbers $2^{250},3^{150},5^{100}$, and $4^{200}$ is:
Option 1: $4^{200}$
Option 2: $5^{100}$
Option 3: $3^{150}$
Option 4: $2^{250}$
Correct Answer: $5^{100}$
Solution : The HCF of the exponentials 250, 150, 100, and 200 is 50. So we can write: $2^{250} = 2^{5\times 50} = (2^5)^{50} = 32^{50}$ $3^{150} = 3^{3\times 50} = (3^3)^{50}=27^{50}$ $5^{100} = 5^{2\times 50} = (5^2)^{50} = 25^{50}$ $4^{200} = 4^{4\times 50} = (4^4)^{50} =

Question : Pipe X can fill a tank in 20 hours and pipe Y can fill the tank in 35 hours. Both the pipes are opened at alternate hours. If pipe Y was opened first, then how much time (in hours) does it take to fill the tank?
Option 1: $\frac{269}{11}$
Option 2: $\frac{286}{11}$
Option 3: $\frac{179}{7}$
Option 4: $\frac{172}{7}$
Correct Answer: $\frac{179}{7}$
Solution : Given: Pipe X can fill a tank in 20 hours. Pipe Y can fill the tank in 35 hours. Let the capacity of the tank = LCM of 20 and 35 = 140 units Efficiency of X per hour = $\frac{140}{20}$ = 7 units Efficiency
Question : Simplify the expression: $\frac{1}{8}\left[\frac{1}{b-1}-\frac{1}{b+1}-\frac{2}{b^2+1}-\frac{4}{b^4+1}\right]$
Option 1: $\frac{1}{b^8-1}$
Option 2: $\frac{8}{b^8+1}$
Option 3: $\frac{8}{b^8-1}$
Option 4: $\frac{1}{b^8+1}$
Correct Answer: $\frac{1}{b^8-1}$
Solution : $\frac{1}{8}[\frac{1}{b-1}-\frac{1}{b+1}-\frac{2}{b^2+1}-\frac{4}{b^4+1}]$ = $\frac{1}{8}[\frac{(b+1)-(b-1)}{b^2-1}-\frac{2}{b^2+1}-\frac{4}{b^4+1}]$ = $\frac{1}{8}[\frac{2}{b^2-1}-\frac{2}{b^2+1}-\frac{4}{b^4+1}]$ = $\frac{1}{8}[\frac{2(b^2+1)-2(b^2-1)}{b^4-1}-\frac{4}{b^4+1}]$ = $\frac{1}{8}[\frac{4}{b^4-1}-\frac{4}{b^4+1}]$ = $\frac{1}{8}[\frac{4(b^4+1)-4(b^4-1)}{b^8-1}]$ = $\frac{1}{8}[\frac{8}{b^8-1}]$ = $\frac{1}{b^8-1}$ Hence, the correct answer is $\frac{1}{b^8-1}$.
