If 70% of 50 students are good in Mathematics. How many students are good in Mathematics & How

many students are not good in Mathematics​

Answer 1

Step-by-step explanation:

70% of 50 students are good in Mathematics

=> 50 × 70%

=> 50 × 70/100

=> 35

Hence 35 students are good in mathematics

If 35 students are good in mathematics out of 50

=> 50 - 35

=> 15

.°. 15 students are not good in mathematics

Answer 2

Step-by-step explanation:

Total number of students = 50

Percent of students good in Maths = 70%

Percent of students not good in Maths = 30%

70% of 50 = $\frac{70}{100} \times 50$

= 35

30% of 50 = $\frac{30}{100} \times 50$

= 15

Therefore, 35 students are good in Maths and 15 students are not good in Maths.
