Option 4: 340
Correct Answer: 354
Solution : Given: 175 : 210 :: 310 : 372 :: 295 : ?
Like, 175 : 210→175 ÷ 25 = 7; 210 ÷ 30 = 7 310 : 372→310 ÷ 25 = 12.4; 372 ÷ 30 = 12.4 Similarly, follow the same pattern for 295 :
Question : A and B together can do a piece of work in 6 days and A alone can do it in 9 days. The number of days B will take to do it alone is:
Option 1: 18 days
Option 2: 24 days
Option 3: 9 days
Option 4: 12 days
Correct Answer: 18 days
Solution : A and B together can do a piece of work in 6 days. So in 1 day, they can do $\frac{1}{6}$th part of the work. Also A alone can do it in 9 days. ⇒ In 1 day he alone can do $\frac{1}{9}$ part
Question : The diagonals of a rhombus are 12 cm and 16 cm, respectively. The length of one side is:
Option 1: 8 cm
Option 2: 6 cm
Option 3: 10 cm
Option 4: 12 cm
Correct Answer: 10 cm
Solution : BD = 12 cm AC = 16 cm We know that the diagonals of rhombus bisect at $90^{\circ}$. So, OD = $\frac{1}{2}$BD = 6 cm AO = $\frac{1}{2}$AC = 8 cm In $\triangle$AOD, $\therefore$ Side, AD = $\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10\ \text{cm}$ Hence, the correct answer is

Question : If $\sqrt{1+\frac{\sqrt{3}}{2}}-\sqrt{1-\frac{\sqrt{3}}{2}}=c$, then the value of $\mathrm{c}$ is:
Option 2: 4
Option 4: 2
Solution : Given: $\sqrt{1+\frac{\sqrt{3}}{2}}-\sqrt{1-\frac{\sqrt{3}}{2}}=c$ Squaring both sides, we get ⇒ $\left (\sqrt{1+\frac{\sqrt{3}}{2}}-\sqrt{1-\frac{\sqrt{3}}{2}}\right ) ^2=c^2$ ⇒ $1+\frac{\sqrt{3}}{2}+1-\frac{\sqrt{3}}{2}-2\times\sqrt{1-\frac{3}{4}}=c^2$ ⇒ $2-2\times\sqrt{\frac{1}{4}}=c^2$ ⇒ $2-2\times\frac{1}{2}=c^2$ ⇒ $2-1=c^2$ ⇒ $c=1$ Hence, the correct answer is 1.
