SSC CGL 2022 PYQ — Question 51

SSC CGL - 01 Dec 2022 - Shift 2 • Quantitative Aptitude • Q51

O is the center of this circle. Tangent drawn from a point P, touches the circle at Q. If PQ = 24 cm and OQ = 10 cm, then what is the value of OP?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 26 cm.

O is the center of this circle. Tangent drawn from a point P, touches the circle at Q.

PQ = 24 cm and OQ = 10 cm

If a tangent is drawn on a circle from an external point, it is perpendicular to the radius at the point of tangency.

In a right-angled triangle,

Hypotenuse² = Base² + Height²

According to the concept,

∠OOP 90°

Hence, OP is the hypotenuse of △OQP which is a right-angled triangle.

Now, OP = √(242 + 102) = 26 cm

The value of OP is 26 cm.
