Question

a is 5% of b, b is 24% of c if a=480 find the value of b and c

Answer 1

guess c=x

b is 24% of c
∴b = x*24/100 = 6x/25

a is 5% of b
∴a= 6x/25 * 5/100
    =3x/250

∵a=480 then
 
      3x/250 = 480
 or, 3x = 480*250
 or, x = 480*250 / 3
         =40000

so,c = 40000 and
      b=6*40000/25 
        =9600

ans= b 9600 ; c 40000

Answer 2

5%of b=a
24%of c=b
So,
5/100 × b= a
=5/100 ×b= 480
• ° • b=480×100/5
• °• b=9600

24% of c= b
So,
24/100 × c =9600
•°•c =9600×100/24
•°•c=40000

So,
b=9600 and c=40000


Hope it helped
