Answer is 54

Explanation:

Let us assume, x and y are the two digits of a two-digit number.
Therefore, the two-digit number = 10x + y and the reversed number = 10y + x

Given:
x + y = 9 ---------1

Also given:
10x + y - 9 = 10y + x
9x - 9y = 9
x - y = 1 -----------2

Adding equation 1 and equation 2
2x = 10
x = 5

Therefore, y = 9 - x = 9 - 5 = 4

Therefore, the two digit number = 10x + y = 10*5 + 4 = 54

Answer is \(33\frac{1}{3}\text{%}\)

Explanation:

Let the CP of each article be Rs.1

\(\therefore\) CP of 3 article = Rs.3

\(\)\(\therefore\)SP of 3 articles = Rs.4

\(\therefore\) Gain % = \(\frac{4-3}{3} \times 100\)

\(= \frac{100}{3} = 33\frac{1}{3}\text{%}\)
