Question : The compound interest on Rs. 4000 for 4 years at 10% per annum will be:
Option 1: Rs. 1856.40
Option 2: Rs. 1600
Option 3: Rs. 1856
Option 4: Rs. 1756.60
Correct Answer: Rs. 1856.40
Solution : Here p = Rs. 4000, r = 10%, t = 4 years. We know the compound interest = $p[(1+\frac{r}{100})^t–1]$ $=4000[(1+\frac{10}{100})^4–1]$ $=4000[(\frac{11}{10})^4–1]$ $= 4000[(\frac{14641}{10000})–1]$ $= 4000[\frac{4641}{10000}]$ $=1856.4$ So, the compound interest is Rs. $1856.40$. Hence, the correct answer is Rs. 1856.40.
Question : The following graph shows the number of cars of different colours in a society.
What is the approximate percentage of white colour cars out of all cars in society?
Option 1: 66.67%
Option 2: 33.33%
Option 3: 15%
Option 4: 25%
Correct Answer: 33.33%
Solution : Total number of cars = 15 + 25 + 5 + 20 + 10 = 75 White cars = 25 Percentage of white cars $=\frac{\text{white cars}}{\text{total cars}}\times100=\frac{25}{75}\times100 = 33.33$% Hence, the correct answer is 33.33%.

Question : If $x+y+z=0$ and $x^2+y^2+z^2=40$, then what is the value of $x y+y z+z x?$
Option 1: –20
Option 2: 5
Option 3: –5
Option 4: –10
Correct Answer: –20
Solution : Given: $x + y + z = 0$ and $x^2+y^2+z^2=40$ ⇒ $(x+ y + z)^2= 0$ ⇒ $x^2 + y^2 + z^2 + 2(xy + yz + zx) = 0$ ⇒ $40 + 2(xy + yz + zx) = 0$ ⇒ $2(xy + yz +
Question : Find the value of $\sqrt{30+\sqrt{30+\sqrt{30+...}}}$ :
Option 1: 5
Option 2: $3\sqrt{10}$
Option 3: 6
Option 4: 7
Correct Answer: 6
Solution : Let $x = \sqrt{30+\sqrt{30+\sqrt{30+...}}}$ So, ${x = }\sqrt{30+x}$ By squaring both sides, we get, $⇒x^{2}=(\sqrt{30+x})^{2}$ $⇒x^{2}=30+x$ $⇒x^{2}–x–30=0$ $⇒x^{2}– 6x+5x–30=0$ $⇒x(x–6)+5(x–6) = 0$ $⇒(x–6)(x+5)=0$ $⇒x=6,–5$ A square root cannot be negative. Thus, $x$ cannot be –5. So, $x = 6$ Hence, the correct answer is 6.
