9) If the height of Ramesh is less by 20% than Suresh, the height of Suresh will be greater than that of Ramesh by how many percent?

25% 30% 32% 28% View Answer

The Correct answer; option (A)

Explanation:

Let the height of Suresh is x and height of Ramesh is y.

Then, height of Ramesh = x – 20% of x

y = x-20/100x

y = x -1/5x = 4/5 x

x =5/4y

Now, height of Suresh – height of Ramesh

= 5/4 y – y = y/4

∴ Height of Suresh will be greater than that of Ramesh by (y/4)/y * 100 %

= y/(4*y) * 100 = 100/4 = 25 %
