If 30% of A = 0.25 of B =1/5 of C, then A:B:C is equal to

If 30% of A = 0.25 of B =1/5 of C, then A:B:C is equal to

If 30% of A = 0.25 of B =1/5 of C, then A:B:C is equal to:

(a) 5:6:4 (b) 5:24:5 (c) 6:5:4 (d) 10:12:15

SOLUTION 1:

Simplify the equation

30/100 of A = 0.25 of B = 1/5 of C

3/10 * A = 25/100*B = 1/5*C

A/(10/3) =B/4 = C/5

Multiply the denominator by 3

A/10=B/12=C/15

A:B:C= 10:12:15
