simple equation

20% of X: that's 0,2*X

if: 0,2*X=300000

you need to multiply it by 5, then:

X = 1500000

20% of X: that's 0,2*X

if: 0,2*X=300000

you need to multiply it by 5, then:

X = 1500000

20% of X: that's 0,2*X

if: 0,2*X=300000

you need to multiply it by 5, then:

X = 1500000

20% means = 20/100 =0.20

0.20X =300,000 divide both sides by 0.20

X = 300,000 / 0.20 =1,500,000.
