In an examination it is required to get 36\% of the aggregate marks to pass. A student gets 198 marks and is declared failed by 36 marks. What is the maximum aggregate marks a student can get? (L.I.C.A.D.O., 2007)
(a)480
(b)550
(c)650
(d)Cannot be determined
(e)None of these
Answer
Answer (as printed): C
Explanation
Let the maximum marks be $x$. $$\text { Then, } \begin{aligned} 36 \% \text { of } x & =198+36 \Rightarrow \frac{36 x}{100}=234 \Rightarrow x=\left(\frac{234 \times 100}{36}\right) \\ & =650 \end{aligned}$$
