Question : X is 30% more than Y and 25% less than Z. If the value of Y is Rs. 300, then what is the value (in Rs.) of Z?
Option 1: 390
Option 2: 400
Option 3: 470
Option 4: 520
Correct Answer: 520
Solution : Value of Y = 300 So, X = $300 × \frac{130}{100}$ = $390$ Now, X = Z × $\frac{75}{100}$ ⇒ 390 = Z × $\frac{75}{100}$ ⇒ Z = $\frac{100}{75}\times 390$ ⇒ Z = 520 Hence, the correct answer is 520.
