Detailed Solution for RRB Group D Mock Test - 34 - Question 61

Let CP = 100

Profit = 240% of 100 = 240

SP = CP+profit = 100+240 = 340

If CP is increased by 30%,

New CP = 130

New SP = Unchanged = 340

On solving (1) & (2)

x = 5 kmph & y = 2 kmph

So the answer is option A.

Slope of the line in option A = -10/6 = -5/3

Slope of the line in option A = -3/-5 = 3/5

Slope of the line in option A = -10/6 = -5/3

Slope of the line in option A = -3/-5 = 3/5

But in option C, 10x+6y-12=0 ∼ 5x+3y−6=0 represents the given line only,

Whereas the line in option A is parallel to the given line.

So the answer is option A.
