50 percent of 30 percent of a number is equal to 150. What is the 40 percent of that number?
Show answer & explanation
Correct answer: B
Explanation
Given:
Number = x
50% of 30% = 150
According to the formula:
30% × 50% × x = 150
(30/100) × (50/100) × x = 150
(15/100) × x = 150
x = (150 × 100) / 15
= 1000
Now, 40% = (40/100) × 1000 = 400
