Explanation

One third of ten percent of 120 = ⅓ of 12 = 4.

Explanation

10% of 90 = 0.1*90 = 9.

One-third of 9 = 9/3 = 3.

Explanation

Given:

Total students = 1500
Present students = 1200

Step 1: Use the formula

Percentage=Present​/ Total ×100

Step 2: Substitute values

=1200​/ 1500 ×100

Step 3: Solve

$$=0.8\times 100=80\%$$

Explanation

All constituent letters (M, A, D, A, M) are checked for symmetry.

While M and A are perfectly symmetrical, D is not.

However, in many contexts of this logic puzzle, MADAM is the intended answer

Because it is a palindrome, even though the letter D technically reverses its orientation in a mirror (appearing as ꓷ).

Explanation

An easy way to calculate a quarter mentally is to halve the number twice:

Step 1: Find half of 120, which is 60.

Step 2: Find half of 60, which is 30. 

Explanation

Given:
The car covers 60 km in 1 hour
Train speed = twice the speed of the car
Time = 30 minutes (½ hour)

Step 1: Find train speed
Car speed = 60 km/h
Train speed = 2 × 60 = 120 km/h

Step 2: Distance formula
$$\text{Distance}=\text{Speed}\times \text{Time}$$Time = 30 minutes = 0.5 hour
$$\text{Distance by train}=120\times 0.5=60\text{ km}$$

Explanation

To complete the series, the pattern is increasing the letters by a certain number each time.

The series goes as follows: B (+3) E (+5) J (+7) Q (+9).

Therefore, the next letter should be 9 letters after Q, which is X.

Explanation

Angle is the odd one out.

Angle is a 1-dimensional measurement,

Rectangle, Square, and Hexagon are 2-dimensional shapes.

Rectangle & Square: 4-sided polygons (quadrilaterals).

Hexagon: 6-sided polygon.

Explanation

We all know that cricket, hockey, and tennis use a stick and a ball that may be of a different shape or size 

But football is played with a ball

Explanation

A circle does not have a side and hence no vertex.

Hence, "circle" is different from all other given shapes.

The square has 4 sides,

A hexagon has 6 sides,

triangle has 3 sides.
