Question

3 If - of A= 50%B=0.4 of C, then A:B:C will be 2 3 यदि Aका =B का 50%=C का 0.4 गुना, तmब A:B:C=? 2​

Answer 1

Answer:

To find a : b : c, b is made same in both the ratios. L.C.M of 4 and 5 is 20

a:b=43=4×53×5=2015

b:c=95=9×45×4=3620

∴   a:b:c=15:20:36

Answer 2

$\huge\bold{♠AnSwEr♠}$

Let the 100% of A be 100

30% of A = 25% of B .... (1)

30% of A = 30

$\large\bold{=> B = \frac{30 \times 100}{25} =120}$

Then,

30% of A = 20 % C .... (2)

$\large\bold{c= \frac{30 \times 100}{20} =150}$

100 % of A = 120% of B = 150% of C

Ratio of A : B : C =10:12: 15
