2. 25% of 80 is as shown below
Therefore, 25% of 80 = 20
3. 60% of 50 is as shown below
Therefore, 60% of 50 = 30
4. 10% of 200 is as shown below:
Therefore, 10% of 200 = 20
5. 20% of 150 is as shown below
Therefore, 20% of 150 = 30
6. 50% of 40 is as shown below:
Therefore, 50% of 40 = 20
Hence,
25% of 80 = 20
10% of 200 = 20
50% of 40 = 20
12% of 250 = 30
60% of 50 = 30
20% of 150 = 30
