Question : Prakash lends a part of Rs. 20,000 at 8% simple interest and the remaining at $\frac{4}{3}\%$ simple interest. His total income after a year was Rs. 800. Find the sum lent at 8%.
Option 1: Rs. 8,000
Option 2: Rs. 12,000
Option 3: Rs. 6,000
Option 4: Rs. 10,000
Correct Answer: Rs. 8,000
Solution : The total income from the two parts of the sum after a year is equal to Rs. 800. Let the sum lent at 8% as $x$. The remaining sum, which is lent at $\frac{4}{3}\%$, is $(20000 - x)$. Use: Simple Interest = $\frac{\text{Principal ×
Question : Simplify $\frac{1 + \sin t}{4 - 4 \sin t} - \frac{1 - \sin t}{4 + 4 \sin t}$.
Option 1: $4\tan t .\sin t$
Option 2: $\tan t . \sec t$
Option 3: $\tan t - \sin t$
Option 4: $\tan t + \sin t$
Correct Answer: $\tan t . \sec t$
Solution : Given: $\frac{1 + \sin t}{4 -4\sin t} - \frac{1 - \sin t}{4 + 4\sin t}$ $=\frac{1 + \sin t}{4(1 - \sin t)} - \frac{1 - \sin t}{4(1 + \sin t)}$ $=\frac{(1 + \sin t)^{2} - (1 - \sin t)^{2}}{4 × (1+
Question : Directions: The following equations have been solved based on a certain pattern. Find the correct answer for the unsolved equation on that basis. If 7 * 4 * 3 = 437, 8 * 6 * 4 = 648, then 4 * 3 * 6 = ?
Option 1: 346
Option 2: 364
Option 3: 643
Option 4: 463
Correct Answer: 364
Solution : Given: 7 * 4 * 3 = 437 8 * 6 * 4 = 648

Question : A thief stole jewelry from a shop at 8:15 p.m. and left on a bike at a speed of 60 km/hr. The police were informed at 8:30 p.m. If the police want to arrest the thief at 9:00 p.m., what should be the minimum speed of the police jeep?
Option 1: 60 km/hr
Option 2: 75 km/hr
Option 3: 80 km/hr
Option 4: 90 km/hr
Correct Answer: 90 km/hr
Solution : Total time travelled by the thief = 9:00 - 8:15 = 45 min = $\frac{3}{4}$ hour Speed of thief = 60 km/hr Distance travelled = 60 × $\frac{3}{4}$ = 45 km Total time travelled by the thief = 9:00 - 8:30 = 30 min
Question : A batsman scores 98 runs in the 17th match of his career. His average runs per match increased by 2.5. What was his average before the 17th match?
Option 1: 58
Option 2: 60.5
Option 3: 63
Option 4: 55.5
Correct Answer: 55.5
Solution : Let the average before the 17th match be $x$. New average after 17th match = $x$ + 2.5 Runs scored in the 17th match = 98 runs Total runs before the 17th match = 16$x$ ⇒ 16$x$ + 98 = ($x$
