Question : The successive discounts of 15% and 20% are equivalent to a single discount of:
Option 1: 25%
Option 2: 28%
Option 3: 32%
Option 4: 35%

Question : If $xy=48$ and $x^2+y^2=100$, then $(x+y)$ is:
Option 1: 12
Option 2: 16
Option 3: 18
Option 4: 14
Correct Answer: 14
Solution : Given: $xy = 48$ and $x^{2}+y^{2} = 100$ We know the algebraic identity, $(x+y)^{2} = x^{2}+y^{2}+2xy$ By substituting the values in the above equation, we get: $⇒(x+y)^{2} = 100+2×48$ $⇒(x+y) = \sqrt{196}$ $\therefore (x+y) = 14$ Hence, the correct answer is 14.
