Question

Two numbers in the form x/y is in such a way that y is 20% more than x and product of them is 2430. Find the sum of x and y.

• A. 99
• B. 93
• C. 87
• D. 81

Answer 1

Answer:

A. 99

y= 120x/100 ….. (1)
xy=2430 … (2)
Substituting (1) in (2), we have
120x2/100=2430
x2= 2430*100/120
=2025
x=45
Then, y= 54
Thus, x+y =99
