If |4x−5|+|3−x|≤2|4x−5|+|3−x|≤2, where x is a real number and maximum value of x is represented in th form of a/b in its lowest form, find the value of a+b? Any better ways of solving

Case 1: x >= 3, the inequality becomes 4x - 5 + x - 3 <= 2 => 5x <= 10 => x <= 2 => No solution in this interval

Case 2: 5/4 <= x < 3: The inequality becomes 4x - 5 + 3 - x <= 2 => 3x - 2 <= 2 => 3x <= 4 => x <= 4/3. So, 5/4 <= x <= 4/3

Case 3: x < 5/4: The inequality becomes 5 - 4x + 3 - x <= 2 => 5x >= 6 => x >= 6/5 => 6/5 <= x < 5/4

So, the maximum value of x is 4/3 => a + b = 4 + 3 = 7

Hi Ritu,

Alligation Rule: This is used to find the ratio of individual components in a mixture. If two components A and B, costing Rs. X and Rs. Y individually, are mixed and the resultant mixture has an average price of Rs. Z, then the ratio of A and B in the mixture is $$\frac{Z-Y}{X-Z}$$

If a, b, c, d and x are positive integers such that $$\frac{a}{b}=\frac{c}{d}$$

If $$a < b$$, $$ \frac{a+x}{b+x} < \frac{a}{b}$$

If $$a > b$$, $$ \frac{a+x}{b+x} > \frac{a}{b}$$

$$\frac{a+c}{b+d}=\frac{a}{b}=\frac{c}{d}$$

$$\frac{a+b}{a-b}=\frac{c+d}{c-d}$$

During the RRB exam, questions from various sections appear randomly and the test is not split into sections with individual time limits. Hence it is very unlikely that they will have sectional cutoffs. GK is a very important subject and upto 40% of the questions are based on it. So, candidates have to prepare well for to answer questions on general awareness.

There is a heavy penalty for wrong answers with -1/3 for every wrong answer. So, it is important that candidates don't guess the answers without enough effort. Around 1 crore candidates have applied for RRB exam this year and there are 18,000 vacancies. So, we estimate that the overall cutoff can be around 50 marks after including the negative marks as well.
