SSC CHSL - 02 July 2024 - Shift 3 • Quantitative Aptitude • Q55

The shortest length of the intercept between the x-axis and y-axis of the equation 6x + 8y - 48 = 0 is:

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 10 units.

6x + 8y − 48 = 0

⇒ 6x + 8y = 48

The shortest distance between the x-axis and the y-axis, we need to rewrite the equation in the Distance form, which is:

⇒ x/a + y/b = 1

⇒ 6x/48 + 8y/48 = 1

⇒ x/8 + y/6 = 1

the shortest distance = a2+b2\sqrt{a^2 + b^2}  

⇒ 82+62\sqrt{8^2 + 6^2}  = 64+36\sqrt{64 + 36}   = 100=10\sqrt{100} = 10 units
