Question

The sum of two numbers is $\frac{23}{20}$ of the first number. The second number is what percent of the first?

• A. $5$%
• B. $10$%
• C. $15$%
• D. $20$%

Answer 1

The correct option is C $15$%

let x be first number and y be second number then,

$x+y=\frac{23}{20}x$

$y=\frac{3}{20}x$

percentage of second number w.r.t first number $\frac{y}{x}\times 100$

=$15\%$
