**Slot -2 – Quantitative Aptitude – Algebra – Functions – Let f(x)=max{5x, 52-2x^2}**

** Let f(x)=max{5x, 52-2x^2}, where x is any positive real number. Then the minimum possible value of f(x) is?**

**Answer:** 20

**Solution:**

For f(x) to be minimum , 5𝑥 = 52 − 2𝑥^2

2𝑥^2+5𝑥 −52 =0

𝑥−42𝑥+13=0

𝑆𝑜 𝑥 = 4

Thus minimum value of f(x) = 5x = 5*4 = 20
