Question : H.C.F of $\frac{2}{3},\frac{4}{5}$ and $\frac{6}{7}$ is:
Option 1: $\frac{48}{105}$
Option 2: $\frac{2}{105}$
Option 3: $\frac{1}{105}$
Option 4: $\frac{24}{105}$
Correct Answer: $\frac{2}{105}$
Solution : Given: $\frac{2}{3},\frac{4}{5},\frac{6}{7}$ Apply formula, HCF of the fraction = $\frac{\text{HCF of numerator}}{\text{LCM of denominator}}$ HCF of 2, 4, and 6 is 2. LCM of 3, 5, and 7 is 105. Hence, the correct answer is $\frac{2}{105}$.
Question : The following bar graph shows the sales of books (in thousands) from six branches of a publishing company during two consecutive years, 2018 and 2019.

Question : The simple interest on a certain sum at the rate of 12.5% per annum for 6 years is INR 13,500 less than the principal. Find the simple interest.
Option 1: INR 13,500
Option 2: INR 54,000
Option 3: INR 40,000
Option 4: INR 40,500
Correct Answer: INR 40,500
Solution : Let the principal be $p$. We know, $\frac{\text{Principal × Rate × Time}}{100}$ = Simple interest ⇒ $\frac{\text{Principal × Rate × Time}}{100}$ = Principal amount – 13500 ⇒ $\frac{p × 6 × 12.5}{100} = p - 13500$ ⇒ $\frac{75p}{100} = p - 13500$ ⇒ $3p
Question : The third proportional of the following numbers $(x-y)^2, (x^2-y^2)^2$ is:
Option 1: $(x+y)^3(x-y)^2$
Option 2: $(x+y)^4(x-y)^2$
Option 3: $(x+y)^2(x-y)^2$
Option 4: $(x+y)^2(x-y)^3$
Correct Answer: $(x+y)^4(x-y)^2$
Solution : Given: Two numbers are $(x-y)^2, (x^2-y^2)^2$. So, let's take $a=(x-y)^2$ = 1st proportion, $b=(x^2-y^2)^2$ = 2nd proportion Now, $c$ = third proportion = $\frac{b^2}{a}=\frac{((x^2-y^2)^2)^2}{(x-y)^2}=\frac{(x-y)^4 (x+y)^4}{(x-y)^2}=(x+y)^4(x-y)^2$ Hence, the correct answer is $(x+y)^4(x-y)^2$.
