Question

यदि A,B से 40% अधिक B,C से 20% कम है तब A:C है

Answer 1

A = B + 40% of B

A = 140/100 * B

Now,

A/B = 14/10

B = C - 20% of C

B = 80/100 *C

B/C = 8/10

SO,

A/C = (A/B) * (B/C) = (14 *8) / (10 *10) = 28 : 25.

Answer 2

Answer:

28:25

Step-by-step explanation:

It is given that A is 40% more than B and B is 20% less than C.

Since B is 20% less than C, so

$B=C-\frac{20}{100}C$

$B=C-0.2C$

$B=0.8C$                  .... (1)

Since A is 40% more than B, so

$A=B+\frac{40}{100}B$

$A=B+0.4B$

$A=1.4B$

Using equation (1), we get

$A=1.4(0.8C)$

$A=1.12C$

Divide both sides by C.

$\frac{A}{C}=1.12$

It can be written as

$\frac{A}{C}=\frac{112}{100}$

$\frac{A}{C}=\frac{28}{25}$

Therefore, the ratio of A and C is 28:25.
