Two numbers are less than a third number by 30% and 37% respectively. How much percent is the second number less than the first?
Answer & explanation
Correct answer: option 4
Let the 3rd number be 100, so, according to the question, the 1st will be 70 and 2nd will be 63.
1st - 2nd = 7
In percentage = \(\frac{7 }{70 }\) x 100 = 10%
