Explanation

current ratio = current assets (C.A)/ Current 

Liabilities (C.L) = 2/1 

s, CA = 2 CL

Now working capital = current assets (CA) minus Current Liabilities (C.L) = Rs 60000

So, C.A - C.L = 60000

2 C.L - CL = 60000

C.L = Rs. 60000

Now C.A = 2 x 60000

C.A = Rs. 120000

Let  3x = 4y  = 5z =k

x = k/3 ,y =k/4 ,z =k/5

x : y : z = k/3 : k/4 : k/5

x : y : z =  20 :15 :12

flag Length 40 Cm &  Width 60 cm Ratio 3:2

         60 : 40

          6  :  4

           3  :  2

Explanation

Enlarge ratio = 7/5 

new length = 5*7/5=7 cm 

New width = 7*7/5=49/5=9.8 cm 

Explanation

Let the numbers be 3x, 5x

3x+4 / 5x+4 = 2/3

​9x+12=10x+8

x=4

∴ the number are 3 x 4 , 5 x 4

=12,20
