The difference between a number and its three-fifth is 274. What is 20% of the number?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 137.
Let the number be x
According to the question
x - (3x/5) = 274
(5x - 3x)/5 = 274
2x/5 = 274
x = 274 * 5 /2 = 685
Hence, 20% of 685 = 685/5 = 137
