​

Answer 1

Step-by-step explanation:

a.

ans- let the total be x

50= 20/100×x

50×100=20×x

5000=20x

x=5000/20

x=250

whole quantity is 250

b.

ans-let the whole is c

75=25/100×c

75×100=25×c

7500=25c

c=7500/25

c=300

hence, the whole quantity is 300

c.

ans- suppose the whole minutes = M

105= 21/100×M

105×100=21M

10500=21M

M=10500/21

M=500

whole minute is 500
