SSC CGL 2024 PYQ — Question 67

The correct answer is Option 2 i.e. 60.

We know that,

The mean proportional between two numbers a and b

x = $\sqrt {a \times b}$

⇒ x = $\sqrt {36 \times 100}$

⇒ x = $\sqrt {6 \times 6 \times 10 \times 10}$

⇒ x = 6 × 10

⇒ x = 60

Thus,

The mean proportion between 36 and 100 is 60
