Question : 60% of 40% of a number is equal to 150. What is the 20% of that number?
Option 1: 175
Option 2: 145
Option 3: 200
Option 4: 125
Correct Answer: 125
Solution : Let the number be $x$. According to the question, $\frac{60}{100}\times\frac{40}{100}\times x=150$ ⇒ $\frac{3}{5}\times\frac{2}{5}\times x=150$ $\therefore x=625$ Now, 20% of $x$ = $\frac{20}{100}\times x$ = $\frac{1}{5}\times 625$ = 125 Hence, the correct answer is 125.

Question : If $\triangle A B C \sim \triangle D E F$, and $B C=4 \mathrm{~cm}, E F=5 \mathrm{~cm}$ and the area of triangle $A B C=80 \mathrm{~cm}^2$, then the area of the $\triangle DEF$ is:
Option 1: 169 cm2
Option 2: 80 cm2
Option 3: 144 cm2
Option 4: 125 cm2
Correct Answer: 125 cm2
Solution : $\triangle$ ABC ~ $\triangle$ DEF, hence the ratio of areas of two similar triangles is equal to the ratio of the square of their corresponding sides. $\frac{\text{area of }(\triangle ABC)}{\text{area}(\triangle DEF)}=\frac{BC^{2}}{EF^{2}}$ $⇒\frac{80}{\text{area of}(\triangle DEF)}=\frac{4^{2}}{5^{2}}$ $⇒\frac{80}{\text{area of}(\triangle DEF)}=\frac{16}{25}$ $⇒\text{area of}(\triangle DEF) = \frac{80 \times

Option 4: 6
Correct Answer: 10
Solution : The slant height of the cone = $\sqrt{8^2 + 6^2}$ = $\sqrt{64+36}$ = $\sqrt{100}$ = 10 cm The slant height of the cone = radius of sector = 10 cm Hence, the correct answer is 10.
