Question

Two numbers A and B are such that the sum of 6% of
A and 5% of B is two-third of the sum of 8%
of A and 10% of B. Find the ratio of A:B​

Answer 1

Answer:

ANSWER

Let the number A is x and number B is y

Then 5% of a is

100

5

x=0.5x and 4% of number B is

100

4

x=0.4y

Then 6% of a is

100

6

x=0.6x and 8% of number B is

100

8

x=0.8y

As per given in question

∴0.5x+0.4y=

3

2

(0.6x+0.8y)

⇒1.5x+1.2y=1.2x+1.6y

⇒1.5x−1.2x=1.6y−1.2y

⇒0.3x=0.4y

⇒

y

x
