2. 110%
3. 80%
4. 60%

Answer 1

Correct Answer - Option 1 : 120%

Calculation:

Class \ Group	Total students	X	Y	Z
A	120	40	60	20
B	100	30	10	60
C	176	48	80	48

 

Number of students in class A = 120

Number of students in class B = 100

The required % = (120/100) × 100 ⇒ 120%

∴ The number of students in class A is 120% of the number of students in class B
