Question : Meena completed a journey in 33 hours. She travels one-fourth distance of the journey at the speed of 60 km/hr and the remaining distance at 40 km/hr. What is the total journey in km?
Option 1: 1220 km
Option 2: 480 km
Option 3: 1440 km
Option 4: 680 km
Correct Answer: 1440 km
Solution : Let the total distance of the journey be D. Meena travels one-fourth of the distance at the speed of 60 km/hr and the remaining distance at 40 km/hr. $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$ The time is taken for the journey as, $⇒\frac{D}{4\times 60} + \frac{3D}{4\times 40}
Question : The length, breadth, and height of a cuboid are 40 cm, 20 cm, and 10 cm, respectively. What is the volume of this cuboid?
Option 1: 16000 cm3
Option 2: 8000 cm3
Option 3: 2000 cm3
Option 4: 4000 cm3
Correct Answer: 8000 cm3
Solution : Volume of Cuboid = lbh Given, Length(l) = 40 cm Breadth(b) = 20 cm Height(h) = 10 cm So, volume of cuboid = 40 × 20 × 10 = 8000 cm3 Hence, the correct answer is 8000 cm3.
Question : The compound interest (compounding annually) on a certain sum for 2 years at the rate of 60% per annum is INR 6240. What will be the simple interest on the same sum for 3 years at the same rate of interest?
Option 1: INR 6800
Option 2: INR 7200
Option 3: INR 7100
Option 4: INR 6500
Correct Answer: INR 7200
Solution : Rate, $R$ = 60% Term, $n$ = 2 years Compound interest = INR 6240 Let $P$ be the principal sum. When compounded annually, Compound interest = $P(1+\frac{R}{100})^n - P$ $⇒6240 = P(1+\frac{60}{100})^2 - P$ $⇒6240 = P(1+\frac{3}{5})^2-P$ $⇒6240 = P(\frac{8^2}{5^2})-P$ $⇒6240 = P(\frac{64}{25}-1)$ $⇒6240
