Difficulty: Easy
Correct Answer: 846
Explanation:
Introduction / Context:
This question focuses on percentage calculations, which are extremely common in competitive exams, finance questions, and data interpretation. You must convert percentages into decimal multipliers and then apply them to the given base values before adding the results.
Given Data / Assumptions:
Concept / Approach:
To find a percentage of a number, convert the percentage to a decimal and multiply. For example, 150% equals 150/100, which is 1.5, and 24% equals 24/100, which is 0.24. After computing each part, we add them together to obtain the total amount requested.
Step-by-Step Solution:
Compute 150% of 460: 150% = 150/100 = 1.5, so 1.5 * 460.Multiply: 1.5 * 460 = 690.Compute 24% of 650: 24% = 24/100 = 0.24, so 0.24 * 650.Multiply: 0.24 * 650 = 156.Add the two results: 690 + 156 = 846.
Verification / Alternative check:
We can verify with approximate mental checks. 150% of 460 is the same as 460 plus half of 460. Half of 460 is 230, so 460 + 230 = 690, which matches. For 24% of 650, note that 25% of 650 would be 162.5, so 24% is a little less, around 156, which agrees with our exact calculation. Adding 690 and 156 clearly gives 846. The logic and the arithmetic both support the final result.
