Question : A car covers 3 successive 2 km stretches at speeds of 20 km/hr, 40 km hr, and 60 km/hr respectively. Its average speed is:
Option 1: 38.56 km/hr
Option 2: 42.12 km/hr
Option 3: 32.72 km/hr
Option 4: 40.50 km/hr
Correct Answer: 32.72 km/hr
Solution : According to the question First stretch at 20 km/hr: ⇒ Time t1 = $\frac{2 km}{20km/hr}=\frac{1}{10}$ hr Second stretch 40 km/hr: ⇒ Time t2 = $\frac{2km}{40km/hr}=\frac{1}{20}$ hr Third stretch 60km/hr: ⇒ Time t3 = $\frac{2km}{60km/hr}=\frac{1}{30}$ hr ⇒ Total time = $\frac{1}{10} +
Question : The value of 3 × [{(11 – 3) ÷ ($\frac{1}{2}$) of 8} + 15 ÷ 3] is:
Option 1: 15
Option 2: 19
Option 3: 21
Option 4: 30
Correct Answer: 21
Solution : Given: 3 × [{(11 – 3) ÷ ($\frac{1}{2}$) of 8} + 15 ÷ 3] = $3 × [\left \{8÷ 4 \right \}+ 15 ÷ 3]$ = $3 × [{2} + \frac{15}{3}]$ = $3 × [2 + 5]$ = $3 × 7$ = $21$ Hence, the

Question : What will be the curved surface area of a cylinder having a radius of 20 cm and a height of 34 cm?(use $\pi$ = 3.14)
Option 1: 3245.7 cm2
Option 2: 4328.98 cm2
Option 3: 4270.4 cm2
Option 4: 4320.6 cm2
Correct Answer: 4270.4 cm2
Solution : The curved surface area of a cylinder with radius $r$ and height $h$ is $2\pi rh$. Given, radius($r$) = 20 cm and height($h$) = 34 cm So, the curved surface area of the cylinder = $2\pi rh$ = 2 × 3.14 × 20
Question : The value of $1-3 \div 6$ of $2+\left(4 \div 4\right.$ of $\left.\frac{1}{4}\right) \div 8+\left(4 \times 8 \div \frac{1}{4}\right) \times \frac{1}{8}$ is:
Option 1: $\frac{69}{4}$
Option 2: $-\frac{69}{4}$
Option 3: $\frac{7}{4}$
Option 4: $-\frac{7}{4}$
Correct Answer: $\frac{69}{4}$
Solution : Given: $1-3 \div 6$ of $2+\left(4 \div 4\right.$ of $\left.\frac{1}{4}\right) \div 8+\left(4 \times 8 \div \frac{1}{4}\right) \times \frac{1}{8}$ = $1-3 \div 12+(4 \div 1) \div 8+\left(4 \times 8 \times4\right) \times \frac{1}{8}$ = $1-\frac{3}{12}+\frac{4}{8}+\left(4 \times 8 \times4\right) \times \frac{1}{8}$ = $1-\frac{1}{4}+\frac{1}{2}+16$ = $\frac{4-1+2+64}{4}$ = $\frac{69}{4}$ Hence,
Question : A sum of money invested at 20% compound interest (compounded annually). It would fetch Rs. 723 more in 2 years if interest is compounded half-yearly. The sum is:
Option 1: Rs. 15,000
Option 2: Rs. 30,000
Option 3: Rs. 20,000
Option 4: Rs. 7,500
Correct Answer: Rs. 30,000
Solution : We have, $R = 20\%$, and $T = 2$. Let the principal be Rs. $P$. When interest is compounded annually, $\text{Compound interest} = P[(1 + \frac{R}{100})^{t}-1]$ $CI=P[(1+\frac{20}{100})^2-1]$ $CI=P[(\frac{6}{5})^2-1]=\frac{11P}{25}$ When the interest is compounded half-yearly, $CI=P[(1+\frac{10}{100})^4-1]$ $CI=P[(\frac{11}{10})^2-1]$ $CI=P[(\frac{14641}{10000})-1]=\frac{4641P}{10000}$ From the question, $⇒\frac{4641P}{10000}-\frac{11P}{25}=723$ $⇒\frac{4641P-4400P}{10000}=723$ $⇒\frac{241P}{10000}=723$ $⇒P
