Question : The HCF of $\frac{3}{4}, \frac{7}{8}$, and $\frac{13}{14}$ is:
Option 1: $\frac{1}{36}$
Option 2: $\frac{1}{56}$
Option 3: $\frac{1}{70}$
Option 4: $\frac{1}{60}$
Correct Answer: $\frac{1}{56}$
Solution : The highest common factor (HCF) of fractions is calculated as the HCF of the numerators divided by the least common multiple (LCM) of the denominators. HCF of the numerators (3, 7, 13) is 1. LCM of the denominators (4, 8, 14) is 56. So, HCF
Question : What will be the remainder when $252^{126}+244^{152}$ is divided by 10?
Option 1: 4
Option 2: 6
Option 3: 0
Option 4: 8
Correct Answer: 0
Solution : To find the remainder when $252^{126}+244^{152}$ is divided by 10, we only need to consider the unit digit of each term in the sum. The unit digit of $252^{126}$ is the same as the unit digit of 2126. Divide 126 by 4 and

Question : The perimeter of the base of a right circular cone is 44 cm. If the height of the cone is 24 cm, then what is the curved surface area (in cm2) of the cone?
Option 1: 550
Option 2: 1100
Option 3: 2200
Option 4: 650
Correct Answer: 550
Solution : The perimeter of the base of a right circular cone is given as 44 cm. The circumference of the base = $2\pi r$, where $r$ is the radius of the base. $⇒2\pi r=44$ $⇒r = \frac{44}{2\pi}=\frac{22}{\pi}=\frac{22×7}{22}=7\;\mathrm{cm}$ $⇒l = \sqrt{r^2 + h^2}$ $⇒l = \sqrt{(7\;\mathrm{cm})^2 +
