A sum of ₹8,000 amounts to ₹9,600 in 4 years at simple interest. Find the rate of interest per annum.
Principal = ₹8,000, Amount = ₹9,600 Interest = 9,600 - 8,000 = ₹1,600 SI = P × R × T / 100 1,600 = 8,000 × R × 4 / 100 R = (1,600 × 100) / (8,000 × 4) = 5%
Reasoning

Correct answer: 48
Verbal
Three pipes A, B, C can fill a tank in 12, 15, and 20 hours respectively. If all three are opened together, how long will it take to fill the tank?
A's rate = 1/12 per hour B's rate = 1/15 per hour C's rate = 1/20 per hour Combined rate = 1/12 + 1/15 + 1/20 = (5+4+3)/60 = 12/60 = 1/5 per hour Time = 1 / (1/5) = 5 hours
Reasoning
If letter positions are summed (A=1…Z=26), PEN equals:
Sum of positions = 35.
Quantitative
Two numbers are in ratio 3:5 and their sum is 56. The larger number is:
Parts = 8. Larger = 5/8 × 56 = 35.
Quantitative
The following table shows the sales of a company over 5 years. If the total sales in 2020 was ₹50,000, and sales increased by 20% each year, find the sales in 2024.
Sales in 2020 = ₹50,000 Sales in 2021 = 50,000 × 1.2 = ₹60,000 Sales in 2022 = 60,000 × 1.2 = ₹72,000 Sales in 2023 = 72,000 × 1.2 = ₹86,400 Sales in 2024 = 86,400 × 1.2 = ₹103,680
